MCQ (Single Correct Answer)

-1

A ray is incident at an angle of incidence i on one surface of a small angle prism (with angle of prism A) and emerges normally from the opposite surface. If the refractive index of the material of the prism is $$\mu $$, then the angle of incidence is nearly equal to :

$${{2A} \over \mu }$$

$$\mu $$A

$${{\mu A} \over 2}$$

$${A \over {2\mu }}$$
