Document Summary
Week 2 lab 2 report: divergence and spatial resolution. The goal of this lab is to measure the dependence of flux on distance for two sources. The photometer was mounted on the rails and a desk lamp was placed at the same height as the photometer (over the 100 cm mark of the ob ruler). The intensity of lift as a function of the distance was measured for multiple positions. The desk lamp intensity was at max and the dmm on auto was on 200 mv and at a. Distances, dmm, and lamp settings were all recorded. The photometer did not saturate (exceed 1: when it was close to the lamp. The expected behavior for an isotropic source was computed with a curve drawn for the theoretical prediction. The data and the curves were normalized using the highest value and plotted. Intensity versus r -2 with r being the distance between source and detector.
