A ray of light is incident on an equilateral prism made of flint glass (refractive index 1.6) placed in air.

Options

  1. AThe ray suffers a minimum deviation if it is incident at angle 53^ .
  2. BThe minimum angle of deviation suffered by the ray is 46^ .
  3. CIf prism is immersed in water ( = 4 3 ) the minimum deviation produced by the prism is 14^0 .
  4. DThe minimum deviation produced by the prism is 23.6^ if it is immersed in a liquid of refractive index =1.2

Correct answer

D. The minimum deviation produced by the prism is 23.6^ if it is immersed in a liquid of refractive index =1.2
