Question

A ray of light strikes the plane mirror at an angle of 72 with the mirror surface. Find the angle of reflection.​

Answer 1

Explanation:

Further on reflection, it makes the same angle i.e. angle of reflection is equal to angle of reflection. Hence, as angle of incidence is 55∘ angle of reflection too is 55∘ and the angle between the incident ray and the reflected ray is 55∘+55∘=110∘ .
