[3.0 pts] {Section B} (a) Draw your experimental setup from part B, labeling the rays (incident ray, reflected ray and refracted ray) and angles (the incident, reflected and refracted angles). (b) Using data from all three incident angles, compute the average value and uncertainty for the refracted angle inside the slab, 0-1. from the given length (please show your work). (c) Create a table of the refracted angle and the exit angle with uncertainties for all three incident angles. Part B: Snell's law All notations are consistent with those in the figure below B4. 30° 6:1 ܀ = . d = (1.24:0.10)cm, w = (3.36+0.16)cm, 0:2 = (29.41.2)°. ܀ 012 45° . d = (1.92+0.20)cm, w = (3.36+0.16)cm, 0+2 = (44.51.1)º. ө = 60° . d = (2.58+0.13)cm, w = (3.36+0.16)cm, 0:2 = (59.51.5)º.
