Q.20 The angle of incidence for a ray of light having zero reflection angle is * 0 O 30 O 45 O 90

Answers

Answered by Sushilvardhan714

1

Step-by-step explanation:

When the light ray is incident normally on a 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. Thus, reflected ray will reflect back in same path as that of incident ray.
