Question

A light ray falls on a mirror and deviates by 60 degree then the angle of reflection will be

Answer 1

Angle of incidence = 90 - angle made with the mirror surface

= 90 - 60=30

if u like comment thanks

Answer 2

Answer:

The light ray falls on a mirror and deviates by 60 degree means the angle betwen light ray and normal on plane are equal thus refracted angle is also 60 degree.

Explanation:

As the refracted angle is 60 degree therefore the incident angle is 30 degree (90-60) thus the reflection angle is 30 degree.
