Question

Define Angle Of Deviation Of The Prism. ​

Answer 1

Answer:

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.
