Unformatted text preview: Physics 450 Modern Optics Laboratory GUIDELINES FOR THE PREPARATION OF LAB REPORTS Objective section of the lab report should clearly point out the goals of the experiment and what they (the students) will learn from it. It should outline the principles and the phenomena being experimentally explored and tested. Procedure part of the lab report should include sketches of the ray diagrams of the experiments, wherever appropriate. It should describe the techniques used for the experimental measurements thoroughly. Data Acquisition section should neatly show all the measurements, as described in the manual. Special attention should be given to record the accuracy of every measurement. Data should be efficiently Presented in tables and graphs and Data Analysis should be done as described in the manual. In addition, it should present average and standard deviation of the measurements, wherever appropriate in Data analysis done by any other method—which extracts additional information from the experimental data, will be worthy of extra credits. Conclusion should present a comparison of different techniques used in the experiment, while pointing out their advantages and disadvantages. In addition, it should include any suggestion, which could possibly simplify the experimental procedure and reduce the sources of errors in the measurements. Distribution of points for a lab report will be as follows: Section Bouts Objective 8 Procedure 12 Data Acquisition 29 Data Presentation > :1-5’ ' Data Analysis 25 " Conclusion 20 Total: 100' i Make sure you include the answers to these questions in the appropriate section of your report. Objective: (~1/2 page) What was the purpose of the experiment? Which theories or principles were tested in the experiment? (briefly) What was done to test them? What were the important results of the experiment? (a short summary) Analysis: (as necessary) Conclusion: Other Tips: What, essentially, did you do in the lab? What experimental results did you get? (in full detail) How exactly do you know what your results mean? How can you be sure of this? (use references) What can your results tell you about the ideas being tested? With what certainty can you draw your conclusions? (1-2 pages) What are the final results of your experiment? What conclusions can you draw'based on these results? How do your results compare to what was expected from the theory? Why do you think your results are as close or as far off as they were? What might be done to improve the results of this experiment? Values should always be presented in the form: (1.23 _-I; .04)x105 m. Give numerical representation whenever possible. Try to avoid using “results were good”. Graphs are a great way to present data, but only if they are labeled clearly enough that I can estimate the values of individual data points! ...
