Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Question

Kyle lays a mirror flat on the floor and aims a laser at the
mirror. The laser beam reflects off the mirror and strikes an
adjacent wall. The plane of the incident and reflected beams

reflected beam strikes the wall at a height b = 34.7 cm
above the surface of the mirror.
Find the angle of incidence 0, at which the laser beam
strikes the mirror.
