Question

The angle between the normal at the point of incidence and the incident ray is known as?

Answer 1

Angle of normal and incident ray:

1. The line which represents the direction of light is called the incident ray.
2. The perpendicular drawn to the surface is called the normal.
3. The angle between the incident ray and the normal is called the angle of incidence.

Hence, the angle between the normal at the point of incidence and the incident ray is known as the angle of incidence.
