A ray of light is incident at an angle of incidence, $\displaystyle i$, on one face of a prism of angle A (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is $\displaystyle \mu$, the angle of incidence $\displaystyle i$, is nearly equal to :
Official answer
(3)
