Question

the incident ray makes a glance angle of 30 degrees wth the mirror.. find the angle of incidence .. angle of deviation .. angle of reflection ... plzz solve it fast tomorrow morning is my exam

Answer 1

Given, the angle with the reflecting surface, that is mirror = 30°.

Angle of incidence = 90 - Angle made with reflecting surface
Angle of incidence = 90 - 30
= 60°

Angle of reflection = angle of incidence
= 60°
