Array of light is incident at an angle of incidence ' i ' on one surface of a prism of small angle A and emerges normally from the other surface. If the refractive index of the material of the prism is ' ', then the angle of incidence is equal to

Options

  1. AA 2
  2. BA 2
  3. CA
  4. DA

Correct answer

C. A

Step-by-step solution

Given: e =0 r₂=0, A=r₁ Since ' i ' is small, Snell's law of refraction can be modified to, aligned & = i r₁ & i= r₁= A aligned
