Question

Define angle of deviation in refraction of light through a glass 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 ). 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.

Explanation:

Answer 2

Angle of Deviation is defined as the angle between the incident and the emergent ray. As the light enters the first refracting surface of the prism it gets refracted and is incident at the second refracting surface and emerges out at an angle of emergence from the prism.
