Prism - Study Material for IIT JEE | askIITians When a ray of light suffers minimum deviation through a prism. Angle of incidence is equal to the angle of emergence. Ray of light passing through the prism is parallel to the base of the prism. Angle of refraction inside the material of prism is equal to half the angle of prism.

Solved: The angle of deviation through a triangular prism is de ... The angle of deviation through a triangular prism is defined as the angle between the incident ray and the emerging ray (angle δ). It can be shown that when the angle of. incidence i is equal to the angle of refraction r' for the emerging ray, the angle of deviation is at a minimum.
