The minimum deviation produced by a hollow prism filled with a certain liquid is found to be 30^ . The light ray is also found to be refracted at an angle of 30^ . Then the refractive index of the liquid is

Options

  1. A2
  2. B3
  3. C3 2
  4. D3 2

Correct answer

A. 2

Step-by-step solution

For prism, s _ m =30^ , r =30^ A=2 r=2 30^ =60^ Refractive index, = ( A+S_m 2 ) A 2 = ( 60+30 2 ) ( 60 2 ) = 1 2 1 2 = 2
