The place you get your hair cut has two nearly parallel mirrors 5 meters apart. As you sit in the chair, your head is 2 meters from the nearest mirror. Looking towards this mirror, you first see your face and then, farther away, the back of your head. (The mirrors need to be slightly non-parallel to see the back of you head, but treat them as parallel.) How far away does the back of your head appear to be from your eyes. Neglect the thickness of your head.
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.
