Question

what is the difference deviation and
produce by prism​

Answer 1

Answer:

When a ray of light passes through a prism, it bends towards the base of the prism. Thus, the path of the emergent ray differs from the path of incident ray. This is called the deviation produced by a prism. The angle of deviation is defined as the angle between the incident ray and the emergent ray.

Answer 2

Explanation:

In the prism, the incident ray and emergent ray are not parallel to each other. The emergent ray is deviated from the direction of the incident ray by the angle of deviation. And, therefore we can see the splitting up of light into its constituent colours on the other side.
