Question

Q1. A light ray is incident normally on a mirror. Angle of incidence in this case is

Answer 1

Answer:

When light ray is incident on plane mirror it undergoes reflection. When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree.

Explanation:

Answer 2

Answer:

When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree.
