Question
Angle of incidence for a prism (μ = √3) is double of the angle of refraction angle of incidence is:-
Options
A.30o
B.60o
C.90o
D.90o
Solution
sin l = √3 sin l/2
2 sin l/2 cos l/2 = √3 sin l/2
cos l/2 = √3/2
l/2 = cos1
=30
l = 60o
2 sin l/2 cos l/2 = √3 sin l/2
cos l/2 = √3/2
l/2 = cos1
=30l = 60o
