Suppose a man stands in front of a mirror as shown in Figure. His eyes are 1.85 m above the floor, and the top of his head is 0.08 m higher. (a) Find the length of the smallest mirror in which he can see both the top of his head and his feet and its height above the floor. Length of the mirror: Height from floor to bottom of mirror: Height from floor to top of mirror:
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.
