Question

Using a plane mirror strip mounted vertically on a board, obtain

the reflected rays for three rays‟ incident at different angles.

Measure the angles of incidence and angles of reflection. See if these

angles are equal. ​

Answer 1

Answer: A ray of light incident normally on a surface is reflected back along the same path. 2)The incident ray,the reflected ray and the normal at the point of incidence ,lie on the same plane.
