A ray of light is incident on one face of a prism at an angle of 50^(@) with the normal . The ray is deviated by the prism through 42^(@) . What is the angle of the prism , if the angle of emergence is 51^(@) ?

Prism||Minimum deviation form||Example on prism

A beam of monochromatic light is incident at i= 50^(@) on one face of an equilateral prism, the angle of emergence is 40^(@) , then the angle of minimum deviation is :

Prism||Dispersion||Deviation

Light rays from a source are incident on a glass prism of index of refraction mu and angle of prism alpha At near normal incidence, the angle of deviation of the emerging rays is

STATEMENT - 1: A light ray passing though a prism it suffers minimum deviation, if after refraction the refracted ray becomes parallel to the base of the prism. and STATEMENT - 2 : In the case of minimum deviation angle of incidence is equal to angle of emergence.
