Question

8. Define 'Angle of Deviation' with a labelled diagram. Also show the angle of
incidence, angle of refraction and angle of emergence.
​

Answer 1

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. The angle of deviation of is the angle of diversion which is produced in the path of the incident light ray striking at the prism .
