Please Explain As Detail As Possible

Part B:

i. (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, ?t1 , 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.

ii. The uncertainty in the calculated value for the refracted angle, ?t1, is primarily due to the uncertainty in the measurement of the length, d. From the video, determine the primary source of uncertainty in the measurement of the exit angle, ?t2 . Explain why this is a source of error.

iii. Use all three refracted and exit angles to calculate the index of refraction of the slab and the uncertainty for each incident angle (please show your work).

Part B: Snell's law All notations are consistent with those in the figure below B4. Bi = 30 . d = (1.07+0.17)cm, w = (3.01+0.18)cm, 0+2 = (30.5+1.2)". 0i1 = 450 . d = (1.56+0.18)cm, w = (3.01+0.18)cm, 012 = (44.5+1.3). 01 = 60 . d = (2.07+0.11)cm, w = (3.01+0.18)cm, 0+2 = (59.6+1.4)
