A Ray of light incident at an angle of incidence 'i' passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its bese and emerges from the prism and angle of emergence 'e'.
(a). How is the angle of emergence 'e' related to the angle of incidence 'i' ?

In minimum deviation position, the refracted ray inside the prism travels parallel to it if the prism is equilateral and the angle of incidence is equal to the angle of emergence. Was this answer helpful?
