In the minimum deviation position, the………. In the prism is……… to the base of the prism.

Assertion : If the angles of the base of the prism are equal, then in the position of minimum deviation, the refracted ray will pass parallel to the base of prism. Reason : In the case of minimum deviation, the angle of incidence is equal to the angle of emergence.

In the minimum deviation position of a prism how are angle of incidence and angle of emergence related ?

A prism of refractive index m and angle A is placed in the minimum deviation position. If the angle of minimum deviation is A , then the value of A in terms of m is
