Question

Write any two characteristics of emergent ray when a light ray passes through a prism

Answer 1

Answer:

1- in refraction through a glass slab, the emergent ray is parallel to the incident ray. 2- Angle of incidence is greater than angle of refraction. 1. ... *The angle of emergence (formed by the emergent ray and normal)= the angle of incidence (formed by the incident ray and normal).
