The requests of expanding agrarian creation should be met while keeping the green house emanations low, and embrace versatile horticultural practices. The quantity of individuals occupied with creation of industrialized merchandise is constntly rising, yet the opposite is valid for the quantity of individuals occupied with essential creation. What's more, the development of quantities of urban tenants relies legitimately upon the food delivered by the country populace. The expansion in the quantity of the urban matured is additionally a reason for concern.

What is a CV And How to Improve Yours!
What is a CV And How to Improve Yours! A CV is sometimes called a vita. If you prefer the more formal name, it is curriculum vitae. Translated, curriculum vitae means, âyour life story.âAs this phrase suggests, a CV contains a summary of professional and/or scholarly facts about yourself your experience, your qualifications, your skills, etc. meant for an entity to consider you for their organization.When organizations are looking to employ for a vacancy, they list the experience and skills that they want from an ideal candidate. They then create a job advertisement, which includes a call for CVs. How close your CV mirrors the experience and skills needed in the job advertisement is a big factor for employers.Hence, when you are searching for new employment, it is important that you have a quality CV on hand. Nevertheless, keep in mind that organizations do not need to open a vacancy for them to receive your CV. Sending them your CV could be a way for you to approach organizations that you love. As a whole, view you r CV as a tool for marketing yourself to potential employers.Note that whether you are just starting your CV writing or are thinking of updating your CV, this is a document that must be updated frequently. Whenever you gain new expertise or change jobs, always remember to update it. © Shutterstock | Petr VaclavekIn this article, we further discuss CVs by highlighting the difference between a CV and a resume. Next, we discuss the typical contents and structure of a CV. Lastly, we give you some tips on how to improve your CV.THE DIFFERENCES BETWEEN A CV AND A RESUMEPeople oftentimes mix-up a CV with a resume. Definitely, they are both professional documents meant to introduce you to an organization, usually for job applications. However, there are a couple of main differences between the two. By knowing the difference between a CV and a resume, you would know better when to use which document.Main DifferencesThe first main difference between a CV and a resume is length. Typically, CVs are two to three (or even more) pages. However, resumes at the entry level are typically just one page long. Persons with extensive experience, of course, can have up to two to three pages. Note that CVs are longer because you are highlighting your academic background. This consists of your degrees, teaching experience, research, publications, awards, presentations, and other accomplishments. Nonetheless, there are large organizations that may request for a CV that is only a one pager if they expect to receive many applicants.The objectives of a CV and a resume are different. A CVâs objective is to establish a scholarly identity. On the other hand, a resume is meant to establish a professional identity. The CV reflects your ability as an academician whether you may be looking to be a researcher, a professor, or a publishing scholar in your discipline of choice. A resume indicates your ability as a professional in a business setting, for example.Another difference between a CV and a resume is the layout. A CV is in chronological order that lists your entire career. The resume, however, can be moved around as it best suits you.Look at this beautiful resume templates and be inspired.[slideshare id=46173277doc=awesomeresumetemplates-150323094821-conversion-gat e01w=640h=330]When to Use a CV or a ResumeSo when do you use a CV or a resume? First, if you are applying for a particular position, see what their requirement is is it a CV or a resume? If the organization does not indicate their preference, choosing between a CV and a resume is pretty simple and straightforward.If you are searching for grants, fellowships, research or teaching positions, or postdoctoral positions in an industry, use a CV. Moreover, applications to graduate school typically ask for CVs.Resumes are ideally used to apply to professional vacancies in business. This is due to the format of resumes. Generally, it consists of three sections your name and contact information, your education, and your professional experience. Each of these parts is fleshed out, with more focus on your job background and responsibilities performed for every position. This format makes it ideal for applying to business-centric positions.Interestingly enough, whether you use a CV or a resum e depends on your country. For example, a resume is the typical application document in Canada and the U.S.A. Canadians and Americans would traditionally use a CV when they apply to jobs abroad or when they search for a position that is oriented towards research or academia. In Ireland, New Zealand, and the U.K., CVs are always used in all kinds of contexts, with resumes not being used at all. In mainland Europe, CVs dominate, with even a European Union CV that is available to be downloaded. For Germany, the CV, known as Lebenslauf, is just one of many documents that German job applicants need to get an interview. In India, Australia, and South Africa, CVs and resumes are interchangeable. However, a resume is typically used for private sector jobs and a CV is usually submitted for public sector vacancies.CONTENT OF A CVThe sections in a CV could be quite lengthy, but the parts described in this part of the article are the main ones. Particularly these are your name and contact infor mation; your areas of interest; your education; your grants, honors, and awards; your publications and presentations; your employment and experience; your scholarly or professional memberships; and your references.Name and Contact InformationIt is necessary to have your name and contact information in your CV. For your contact information, you can include the contact details of your current organization or employment. However, if you do not want your boss or your colleagues to know that you are looking for other jobs, it is best to put in your personal contact information. Your contact information are typically your name, your address, your birthday (however, based on age discrimination laws, this is not important), your phone number, and your email. In addition, make sure that your contact information is up-to-date. If you have an outdated email or phone number, how would you expect your would-be employers to contact you?Some people still struggle with the issue of including a phot o in their CVs. British CVs usually do not need a photo that is, unless you are an actor. For European countries like Belgium, France, and Germany, it is typical to include a photo that is passport-sized on the upper right hand corner of the CV. However, in the U.S.A., photos are discouraged because it might go against equal opportunity laws. This is because a photograph can make it easier for someone to reject a candidate based on his or her age, sex, or ethnicity. If the prospective employer asks for a photograph, make sure you provide a head and shoulders picture. You must be smiling and dressed appropriately.One really awesome tip from Ramit Sethi: Write your CV like a narrative. Areas of InterestWe are not talking about your interests in tennis, swimming, and reading. We are talking about your academic interests. Hence, list down your different areas of academic interests. What research fascinates you? What kind of intellectual activities do you want to pursue or have pursued ?A tip for making your areas of interests shine is to figure out more about the organization or department you are applying to. What kind of research papers do they publish? What are their research interests? This would help target your areas of interest. You may even underscore any research accomplishments and findings you have uncovered through your work and/or education. This demonstrates that your expertise complements their organization. The organization can also judge whether you are familiar with their technical jargon.EducationList your degrees, whether they may be in progress or earned. Remember to include also the educational institutions and graduation years. List this in order of the most current and of course, most significant, first. If you have a PhD, put in the full title, even the names of your supervisors. You may even choose to include the title of your thesis or dissertation. If you like, you can include your grades if they are exceptional.Remember, do not go ov erboard with your education. Do not incorporate qualifications that are not significant for the job position. So which parts of your education should you include on your CV? If you just left school, put an emphasis on what you achieved while you were in school. If you are a recent school leaver, the positions you are applying for probably will not need a lot of direct work experience. Hence, use the CV to market yourself. Make sure to include your English and Math subjects (if you did well in them), since they are usually important to almost all jobs.If you just left university, focus on your university and degree. Keep in mind that if you have many subjects, simply list your average grade. This can save space in your CV, not to mention make it easier to read and neater. Indicating individual subjects are not completely essential, but they can raise your chances of getting the interview, if the subjects are connected to the job vacancy.If you are in the process of studying, data on your present area of study is important. Include grades that you predict you might receive, especially for relevant subjects. In this manner, recruiters can confirm if you have particular knowledge of their industry.If you have professional qualifications and have not been in school for a while, detail your most current educational qualification, while leave the others brief (do not go as far back as your preschool days!).Grants, Honors, and AwardsIndicate all of your grants, honors, and awards due to your work, whether it may be for research or for teaching. Demonstrate that you not only do your job, but you do it well enough to receive these accolades.In indicating your grants, honors, and awards, list scholarships that are both need-based and merit based, whether they may be regional or national in scope. Also, include awards from your school or from your department and awards for service or academic accomplishment. For every honor, include the award name and a brief description of its objective if it does not seem evident from the context. In addition, include the date that you received the honor.Publications and PresentationsEnumerate your publications books and journal articles. Give the title, co-authors (if applicable), date, and location of the publication. You may also include electronic publications and journals that were peer-reviewed. Make sure to indicate whether the publication is an electronic version.Also, include the presentations you have given for conferences and forums. This may be academic presentations or public presentations. For every presentation, put in the title, sponsoring organization or event, format (poster, lecture, panel presentation, seminar), and date. Do not go into too much detail by including all of your class presentations. Instead, include presentations you made that are independent research.If you have numerous publications and numerous presentations as well, consider having one section for publications and another se ction for presentations. In this manner, you get to establish that your work has netted public notice.Employment and ExperienceAs a CV leans towards your academic background, your employment and experience section should indicate your experiences in a teaching setting, a laboratory, on the field, during volunteer work, leadership, or other significant experiences.Make sure that your employment and experience is in reverse chronological order and includes the name of your employers, the positions you held, and the length of service in the organization. To go into detail, include your achievements and duties, however, choose only the significant information. In other words, be concise.Notice that we highlight that you put in your achievements. While it is tempting to list only your duties and responsibilities, your achievements are the ones that set you apart from the others. So when you are writing your employment background, assess your career and successes. Ask yourselfdid you exec ute any changes for the better? Were you able to solve a huge challenge? Make sure that this is incorporated in your employment background. Moreover, if you are describing your achievements, make use of action words like âplanned,â âdeveloped,â or âorganized.â Also, try to connect your skills to the position. In addition, as you list your accomplishments, always make them connected to the job vacancy.Some more tips on writing a great resume. Scholarly or Professional MembershipsList the scholarly or professional organizations wherein you are a member. Accomplish this by writing out the full name of the organization. In addition, include your level of membership. This is important because recruiting managers are always searching actively for that extra âoomphâ from would-be employees. What this indicates is that the candidate may be dedicated to the industry enough to join these organizations.Consider that the value of a scholarly or professional membership depends on the recruiterwhether or not he or she recognizes it. If you have memberships that you think are obscure, make sure you know the organization well enough when you are called in for an interview. Avoid indicating memberships in social clubs such as the Rotary Club or a golf club.If you hold a position or office in the organization, indicate it in this section or move it to the experience section. This is upon your own discretion.ReferencesIn this section, indicate the persons who can write recommendation letters for you. This must include their contact details. Customarily, two references are suitable an employer and an academic. Nevertheless, many employers do not check references at the application stage. Hence, unless the job advertisements particularly requests for your references, you can remove this section from your CV entirely. In addition, if you are running out of space, you can just state, âReferences are available upon request.â On a related note, if you have a dossi er with confidential references, mention it in this section as well. STRUCTURE OF A CVIn structuring your CV, you must consider the type of CV you use, the order in which you place your information in your CV, and the format that your CV takes.

You can include details of your dissertation like its title with even a brief description.Next, know what jobs you are interested in, as well as your strengths. Put this in your CV. As you figure out what comes after your education, keep in mind that the earlier it is in your CV, the more emphasis you are putting on that informati on. The most important data comes first.If you would like to apply to a university that focuses on research, it is important to highlight conference presentations, research projects, particularly publications.

What this means is that your CV has clarity and blocks of information that make sense.Moreover, use common strategies in formatting CVs like parallelism and gapping. Parallelism focuses on the structure of your phrases or sentences that is made consistently throughout your CV. For example, if you use verb phrases in one part of your CV, do the same in the other parts of your CV. Gapping uses inc omplete sentences so you can show your information in a manner that is concise and clear.If you are thinking of using bullets, do so depending on how your CV will look as a whole. For example, if you have descriptive sentences that run two to three lines in your CV, use bullets to separate them. However, if you have short phrases in your CV, having bullets can leave much white space on your CV that can be used more effectively in other instances. Check the Print Preview on your word processing application to make sure that your CV does not look too crowded or misaligned. Just remember that your CV has to be concise yet exude readability. Always use this rule of thumb when putting your CV together.For font sizes, use typically used fonts like Arial or Times New Roman. Other unconventional fonts might be good for other projects, but not for your CV. This can distract your reader from the content you want them to focus on. With the exception of your name, try to use a uniform font size throughout the CV to keep your reader concentrated on your accomplishments.Remember, there is no one format for a CV. This is your document and this can be structured however you like. You have to keep in mind what you should focus on, depending on your discipline. Know what the most important factor in your discipline is and conform to their standard conventions. Nevertheless, how do you know what are the conventions of your industry? A good place to begin is to check out examples of CVs of people within your discipline who have been on the job market recently.You may even look for examples of CVs on the internet. A lot of professionals and professors post their CVs online on bulletin boards, faculty web pages, employee pages, etc. These documents are great templates for creating your CV. There is a caveat, however. Do not follow these examples to the smallest detail. They should, instead, be used as strategy sources.HOW TO IMPROVE YOUR CVIf you want to improve your CV, here are a couple of helpful tips:Plan Ahead. Always prepare your CV ahead of time, even before you spot any new job opportunities. Make sure to submit your application earlier than the closing date, so you will not be in a rush. By being prepared, you already have a good base to work on. You can simply customize your CV to a particular job opportunity without pouring in too much work on your CV.Double-Check and Edit. It may seem so repetitive, but there are many individuals who ignore this advice: make sure that you completely check and edit your CV. Even better, get someone to check the entire document for spelling and grammar errors, as well as clarity. Mistakes in your CV can lead it right to the recycle bin.Customize. Since a CV needs to be customized per job opportunity, make sure you are sending the right CV version to the right organization. It would seem quite bad, for example, if you focused your CV on your ability to follow leadership, but the company is actually looking for someon e who is more of a self-starter.Make it Interesting But Clear. Always guarantee that your CV is interesting and easy to read. Remember that employers and recruiting managers go through many CVs. So, do not make it challenging for them. Make it a pleasure for them to go through your CV. Think of what font would be good for your CV, as well as the size and the density of the text. Do not go beyond the color black.Make it Easy to Read. Use short blocks of text and bullets. Nevertheless, make sure that you do not use them for long lists. Always check if your document looks good by doing a Print Preview.Use Tables Sparingly. You can use tables for texts that are only of small amounts. Do not go overboard.Show Life Experience. Keep in mind that your life experience is almost as significant as your job experience. You can demonstrate that you know about budgeting, project management, and communication skills through your day-to-day life. Just frame it in a professional manner in your CV.As k for Help. Do not hesitate at asking your colleagues and friends for your strengths and if they have any advice or comments on your CV.

nbsp;nbsp;nbsp;nbsp;nbsp; Article Review nbsp;nbsp;nbsp;nbsp;nbsp;Child development is a very important in todayââ¬â¢s psychology. That is why it is not surprising that so much research has been developed on that topic. In the article ââ¬Å"Transforming the Debate About Child Care and Maternal Employmentâ⬠the author, Louise B.

He concluded that ââ¬Å"emotional disorders and intellectual retardation (â⬠¦) were the consequence of a wide range of factorsâ⬠(Silverstein, 1027). Unfortunately, Rutterââ¬â¢s findings were not accepted by the research community and the scientists kept gathering studies influenced by Bowlbyââ¬â¢s theory. nbsp;nbsp;nbsp;nbsp;nbsp;Later research conducted by many professionals focused on the child-care disruption of attachment process of child to mother and the degree of that attachment in children put through child care program.

Proving the lens formula Essay Example
Proving the lens formula Essay When light passes from air to a denser material it slows down. In a concave lens the light has to travel further through the middle then through the sides. This has the affect of pushing the waves back in the middle and forward around the edge therefore effectively adding curvature to the wave. A similar thing happens when passing through a concave lens but obviously vice-versa, taking away curvature of the wave. The curvature that the lens adds or takes away is the Power of the lens, measured in dioptres. P=1/f, P is the power of the lens and f is the focal length. The focal length of a lens is the distance from a lens to its focal point, which is where the image of a distant object is formed. The shorter the focal length the more powerful the lens. The following formula is what I am going to attempt to prove that it is valid. It is used to give the focal length, and hence where the image is focused. 1/v+1/u=1/f We will write a custom essay sample on Proving the lens formula specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Proving the lens formula specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Proving the lens formula specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Where v is the distance from the lens to its focal point, u is the distance from the object to the lens and 1/f is the power of the lens. This follows from the above, the power shows how much curvature is added to the wave. As a wave moves further away from an object the curvature of it decreases. This formula may also help me with my progress, as I can use it to calculate the magnification of the lens. m=v/u (when in focus) Where m is the magnification, v is the distance from the lens to the image and u is the distance from the lens to the object. The further away the image is from the lens the lower the magnification, and the closer the image is to the lens the higher the magnification. Hypothesis The lens formula for a convex lens valid. Apparatus I will use the following equipment during me experiment. A Convex lens and lens holder Small convex lens used to focus the image on the screen. Small plastic holder used to keep the lens in place. A Metre rule Will be used to measure both the object distance (U) and the image distance (V). It has millimetre units, although large and hard to take a precise measurement in mm. A 30 cm rule Will be used to increase the accuracy of the measurements, where the metre rule proves difficult to use to get an accurate result. A Small screen Flat white screen on a stand, used for the image to focus on. Image distance measured from the front of the screen. A Light source (Mains or Low Voltage) small Lamp, 40-watt bulb. Used to emit light and is part of the object. A wire mesh on a stand Used to create a clear, sharp focus-able image that I can take measurements from. Placed in front of the light source. Jack Webdale 02/05/2007 Page 2 Most of the apparatus I will use are self explanatory due to the background information. I will use the Wire mesh on a stand as part of the object, as I am satisfied that it will be easy to produce a clear, sharp image with it. If I was to use A light bulb with text printed on it, it may be harder to get a clear image as if I used ink, it may smudge or become blurred due to the heat of the lamp. I have also chosen to use a 30cm rule as well as a metre rule, as the metre rule may be inaccurate or cause problems when trying to measure to mm. A 30cm rule could be used to do this easily and to a better degree of accuracy. Prediction I would choose to predict that the formula is valid. Avoiding the fact that people have used the formula for years, especially opticians, and I gather it must work as they still use it! However, my task is to prove that it works. The diagram below shows what occurs when light travels through a converging lens. It shows where the focal points image and object distances are represented. Due to the proportions of the diagrams I have studied, it would seem logical that two reciprocals added together would produce a reciprocal which its decimal value would be less, which confirms the diagrams. Therefore, I believe that my experiment, if done accurately, should prove that the lens equation is true. Diagram of apparatus Consideration of the variables This Experiment relies heavily on accuracy of measurements and distances. Therefore, it is imperative that these are not affected while measurements are taken. I will take 2 measurements of Jack Webdale 02/05/2007 Page 3 Each required distance to ensure I should not have made an error. Ideally, if I would have time, I could do an average of results for one distance to ensure a reliable result each time. However, I feel checking twice, taking the distances where the image appears focused, and taking a middle value, will give reliable results. Another Variable that could affect the point where the image is focussed is exterior light not emitted from the object (lamp and mesh). Therefore, I will compose my experiment in a dark room, so that sunlight will not affect the image, and this should also help me to get a clearer focus of the image on the sheet. I will stick all apparatus to the bench when they are not being used, so that the non-variables are not affected or altered. Method Before I begin the real experiment, I have chosen to perform a preliminary experiment to discover a suitable range of distances I will get results from. I will also have an idea of the power of the lens, so I can judge its minimum and maximum distances to get a clear image on the sheet. To do this I will set-up the apparatus as shown in the diagram of apparatus, And I have chosen to make the Object and the lamp a constant position, due to the wires etc and difficulty of shifting it about all the time. Therefore, the Lens and the image sheet are the elements that I will move to focus the image. Preliminary research I began with a crude test, to get an approximate result for the focal length of the lens. I simply got a piece of paper, put it against a ruler, and with the lens; I placed it in front of a window, and focussed the image on the paper. I then had a measurement of approximately 15 cm. This would help me greatly in my experiment, as it would indicate immediately any results way off the mark, considering the variables and errors. I then also set up the apparatus as shown in the diagram, and used them to determine what distances I would use in my experiment. I placed a metre rule on the bench, and put on one end, the screen that the image would focus, and at the other, the object. I decided that I would not exceed this Object to Image (U V) distance, as measuring over a metre would cause problems, as I would need to have to metre rules, increasing the chance of making the results inaccurate. I then discovered how close I could put the lens to the object, until I could not get a focus on the screen (Where The focal length equals the object distance, and the image distance = ?). This was in between 13-18 cm for the object distance. Preliminary research Summery Part 1 * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Place the lens on a flat surface, facing a window so that light from outside travels through the lens. Place the screen at the opposite end, so that it looks similar to the diagram above, but using the outside as the image. Move the screen until an image (Real, inverted) is focussed on the paper. * Measure the image distance, using a 30 cm ruler. (This is the approximate focal length). Part 2 * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Set-up the equipment as shown in the diagram of apparatus, placing the object at one end of the metre rule, and the screen at the other (this is the maximum object to image distance). * Move the lens close to the object, and experiment with the lens and the screen until it is Jack Webdale 02/05/2007 Page 4 Impossible to get a focussed image on the screen. * Find the bounds which this occurs, and record the results (This is the area where the focal length is approximately the same as the object distance). There is no need for a table of results for this preliminary experiment, as not many results are taken, they are merely to give an idea of the expected results in the real experiment. Real Experiment * Collect all of the equipment displayed in the diagram of apparatus. * Check that the lamp works, and that the lens is not cracked or dented. * Set-up the equipment as shown in the diagram of apparatus, placing the object at one end of the metre rule, and the screen at the other (this is the maximum object to image distance). * Turn on the lamp; line it up with the mesh so that the lens, screen and the object line up against the metre rule. * Keeping the Screen and the Object stationary, move the lens up and down the metre rule until a clear, focused image of the mesh can be seen on the screen. * Measure the object distance to the lens, using the white mid-point line on the lens holder as a marker, then measure the Image distance, using the front of the screen as the marker. Use the 30cm rule so that the mm can be measured as accurately as possible. * The lens can move around 5 mm and still produce a clear and focussed image on the screen. This is merely due to the sensitivity of our eyes. For the following results, keep the object stationary, and move the screen 10 cm down the metre rule, decreasing the distance to the object each time. Measure the distances. For the Image distance, you will need to record two results, where the image beings to lose focus between the 5mm focus gap. These results can be used to obtain a midpoint, where the real focus is occurring. * Repeat this so 8 records have been taken. For each, be-aware of the results been recorded, and be aware that the focal length is approximately 15mm, and repeat any result that appears irregular. * As the experiment goes on, eventually a focused image will be impossible to obtain. This is where the image distance is equal to the focal length. You should not try and record results at this point and beyond. Table of results example My table will take this form: U (object distance) cm Min. V (Image distance) cm Max. V (image distance) cm Avg. V (image distance) cm 1/U + 1/V = 1/F F (Focal length) cm . . . . . . Risk Assessment All things considered, there are little risks presented with this experiment. I feel confident no special precautions need to be taken to ensure the safety of people partaking, or working near the experiment. The are few dangers which in extreme circumstances could cause a problem is the Light bulb. First because of the heat and the risk of burning a hand, which can be avoided by using a metal cover, not touching the bulb, and a cap over the cover to expose little of the lamp. The electricity supply could also be a danger, but I will ensure the wires are out of the way of tripping over, pulling the plug and causing any problems. Jack Webdale 02/05/2007 Page 5 The Second is the possibility of a dropped lens, leaving shards of glass on the floor, and in extreme circumstances these shards going into someones eye. To avoid this as much as possible, the lens will be placed in its holder, away from the edge of the bench. Also, if the lens is dropped, it is to be swept up immediately and a new lens to be used. The Results The experiment worked out sufficiently, although one result, where the object distance was 20.6cm, the Avg. V Distance was around 60.4 cm. I knew this must be an error due to the pattern of the decreasing V distance, and the Focal Length of this result would have worked out to be 15.361 cm, which is quite far out from the other results. Due to this I repeated the experiment for this result, using the same apparatus, which I had numbered in case this occurred. The Graphs of these results are on a separate sheet of graph paper. To be precise, I performed each measurement twice to ensure I hit the mark each time. The second measurement was basically a check for the first. I could not take results more than two decimal places for accuracy, as I merely used my own vision and judgement. If however, I had Specialised measuring equipment, this could have been more accurate. Evaluation and Conclusion For plotting the graph, I also needed the separate data for 1/V and 1/U. So I put them in the following table to allow me to successfully draw the graph. After analysing the graph, it can be seen that a strait line can be drawn through the points. This means that the Object distance (U) is Inversely proportional to the Image distance (V). Thus we can say that when any result is taken for say U, put in its reciprocal form, and then added to the reciprocal of V, the result is always the reciprocal of the focal length of the converging lens being used (discarding errors and inaccuracy in this statement). On my graph, it can be seen that the line doesnt travel exactly through every point, but in all cases travels through the error box. This shows that if the results were perfectly calculated without any chance of error, all the points would lie on a strait line. It also shows that although I conducted my experiment as accurately as possible, small errors did occur. With the graph, I have determined that the equation of the line is 1/v = (-1)1/u+1/f. From this statement the gradient of the line is always -1, and this is always the case wha tever the reciprocal of the focal length. Also, due to the -1 gradient, the X-axis intercept is also the reciprocal of the focal length. With the graph, I can determine the experiment was successful, as the straight line travels through both axis and at almost the same points. On the Y-Axis 1.167cm and on the X-axis 0.066cm. They both give a focal length of approximately 14.9cm Knowing that the focal length is approximately 15cm, I can conclude that my experiment was successful, and thus proves that the lens formula 1/U + 1/V = 1/F is valid. I decided not to put error bars on my graph, as I was not using the whole values of v and u, where I knew the errors spread over a 0.5cm distance for each measurement taken. However, even though I took middle values of v, it is still evident that errors took place. If I were to repeat the experiment, I would choose to take two values of u, the object distance as well as v then take the middle value. This may also reduce the chance of inaccuracy due to the human eye. There are little ways in which I could improve this experiment, except take many readings of a result, then take an average value. Doing this for every measurement taken, however, would be very time consuming, and if one reading happened to be far out, the average would not be that accurate.
