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

A submarine is 2.90 x 102 m horizontally from shore and 1.00 x 102 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 2.08 x 102 m from the
shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level.
