A ray of light is incident on a 60∘60^\circ prism at the minimum deviation position. The angle of refraction at the first face (i.e., incident face) of the prism is

Multiple Choice Options

  • A zero
  • B 30∘30^\circ
  • C 45∘45^\circ
  • D 60∘60^\circ

Step-by-Step Verified Solution

Angle of prism, A = r 1 + r 2 For minimum deviation r 1 = r 2 = r _ A = 2r Given, A = 60� Hence, r = A 2 = 60 _ 2 = 30 o
