Question
A ray incident at an angle 35o on a prism emerges at an angle 37o as shown. If the angle of incidence is made 50o, which of the following is a possible value of the angle of emergence?
Options
A.35o
B.42o
C.40o
D.38o
Solution
δ2 < δ1
δ1 - i + e - A
= 53o + 37o - A = 90 - A
δ2 < 90 -
50 + e - A < 90 - A
e < 40o
