Question

what is angle of deviation?? explain

Answer 1

The angle of deviation through a triangular prism is defined as the angle between the incident ray and the emerging ray angle. It can be shown that when the angle of incidence is equal to the angle of refraction for the emerging ray the angle of deviation is at a minimum.

Answer 2

ANSWER....

Angle of deviation is the deviation of moving objects which can be ray of light or solid object from its path after refraction or reflection.
