Reflection from Plane Mirrors
Plane Mirrors
Plane mirrors are commonly used as looking glasses. We use them while dressing, Combing, and so on. A plane mirror is made from a glass plate, a few millimetres thick. One surface of the glass is polished to a high degree of smoothness, forming the front surface of the mirror. The back surface is silvered, i.e., coated with a thin layer of silver, aluminium or some other shiny, opaque material. A coat of opaque paint behind this layer protects the silvering. When light from an object falls on the front surface, most of it enters the glass plate and falls on the silvered surface.
Reflection From Plane Mirrors:
An image by a plane mirror is formed when light from the object reaches our eyes after reflection from the plane mirror. As the light enters our eyes we can see all the details of the object. Plane mirror is the surface with flat reflecting surface.
