A lighthouse on a cliff sits 60 m above the surface of the water and 30 m from the rocky coast. A sailor stands on the bow (front) of a ship, with an eye level 20 m from the surface of the water. a.How far is the sailor (and their vessel) from the rocky cliffs? b.From this same distance, at what angle must the sailor look to look into the beacon of the lighthouse?

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.
