Question

what is angle of incidence, when equilateral prism is in minimum deviation?​

Answer 1

Answer:

60°

Explanation:

The prism is an equilateral prism so all of its angles will be 60∘. The picture shows a ray of monochromatic light passing through a glass prism surrounded by air. When the incident falls on the surface of the prism, it gets refracted towards the normal.
