Question

A ray incident at a point at an angle of incidence 60 enters a glass sphere of μ=3 and is reflected and refracted at the further surface of the sphere. The angle between the reflected and refracted rays at this surface is :
  1. 50
  2. 90
  3. 60
  4. 40

A
40
B
90
C
50
D
60
Solution
Verified by Toppr


Using Snell's Law at point P we get:-
sin 60osin r1=3
sin r1=12r1=30o

As we know that r1=r2r2=30o

Using Snell's Law at point Q we get:-

sin 30osin i2=13i2=60o

Since reflection at point Q occurs
r2=r2=60o

Let angle between the refracted ray and reflected ray be α
α=180o(r2+r2)=90o

Hence option (B) is correct.
