A) Apply Snell's Law and calculate the theoretical angle of refraction for two cases; that is, for a case where n₁>n₂ and a case where n₂>n₁

N1= 1

and N2= 1.6

Ask if you need any more info, thank you.

B) Use Snell's Law to calculate the critical angle and compare to the experimental value

for part B the larger index was 1.6

the others were 1, 1.33, and 1.5

Any more info needed can be provided
