Question

I know how to do refraction problems involving different layers but I don't quite understand how to do it with prisms. Could you walk me through it? Thanks!

1.) The light beam in the figure below strikes surface 2 at the critical angle, ?_c = 42

Answer 1

1)

R1 = 90-72 = 18

ref. index = 1.494

i1 = 27.49 deg.

90 and 72 are the angles around the inner incident angle to normal found by geometric math. ref. index is found from the critical angle. Then n1sin(theta1)=n2sin(theta2).

2)

52 58 2 By snetl's a sin S8 .46 go.. 62-57.드 22-43 _and_-.1.46
