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

The triangle is isosceles, and alpha (the angle at the top of the triangular prism) is 50.4 degrees.

What is theta? (the angle below the horizontal that the ray makes emerging from the prism on the right)?
