The correct relation between the refractive index ( mu ) of the material of prism (A) and angle of minimum deviation ( delta ) is

(a) Draw a ray diagram showing the passage of light through a glass prism. Hence obtain a relation between the angles of deviation, incidence and emergence and angle of prism. (b) Show that no ray can pass through a prism whose refracting angle A is greater than twice the critical angle for the material of the prism.

For small angled prisms, (whose refracting angle (A) is less than 5"), the correct relation between refractive index ( mu ) of material of prism and angle of deviation is

The refracting angle of a prism is A and refractive index of the material of the prism is cos(A//2) . The angle of minimum deviation is
