Optics Logging the Experimental Data It is strongly recommended to read the lab note some days before doing the experimentation, and to try to understand the purpose and procedures in advance. Before starting the measurement, talk to your partner and make a plan. Discuss all measurements and input numbers needed towards the final result. Estimate which data inputs are most critical in terms of precision of the final result. You need to LOG carefully all details of the setup, the experimental conditions, and the procedures you followed. Note the time-of-day for the various measurements, and all relevant environmental and experimental information. This is absolutely crucial if you later on want to analyze the data, reconstruct what went awry, or deduct and estimate possible sources of errors. During the lab you should check your data regularly with back-of-the-envelop calculations to see if the results obtained are within expectations, and not wildly off. file:///C|/Documents%20and%20Settings/Linda%20Gra...Brook%20HEP-H2/PHY132%20Sp03/PHY132lab_notes.html (1 of 10) [2/4/2008 3:42:15 PM]
