A submarine is 285 m horizontally from the shore of a freshwater lake and 111 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 201 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. Draw a diagram of the situation, identifying the two triangles that are important in finding the solution.
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.
