A ray of light is incident at an angle ' i ' on one face of prism of small angle 'A' and emerges normally from the other surface. ' ' is the refractive index of the material of the prism. The angle of incidence is

Options

  1. AA
  2. BA 2
  3. CA 2

Correct answer

A. A

Step-by-step solution

For small angled prism _ m =( -1) A Again i+e=A+ _ m = A-A Here e=0 i=A+ _ m =A+ A-A= A
