Question

A ray of light hits a plane mirror at 60° from the normal. What is the angle between the reflected ray and the surface of the mirror?; 1) 30° from normal; 2) 90° from mirror; 3) 90° from normal; 4) 30° from mirror

Answer 1

90°from mirror

So ,(the reflected angle that is form with the normal must be added with the angle that is made from the incidence ray)

=(60°+30°)

=90°
