Reflection of light

REFLECTION OF LIGHT

We see objects if light from it enters our eyes. Some objects such as the Sun,

electric lamps and candles make their own light. We call these luminous sources.

Most things that we see do not make their own light but reflect it from a luminous

source. They are non-luminous objects for example this page, teaching board and

the Moon.

Reflection of light is same as for other types of waves, such as reflection of water

waves in ripple tank. Most objects reflect a certain portion of the light falling on

them, mirrors reflect more light and in a regular manner. An ordinary mirror is

made by depositing a thin layer of silver on one side of a piece of glass and

protecting it with paint. The silver at the back of the glass - acts as the reflecting

surface.
