Meghna Thapar 5 years, 7 months ago

Light is a form of energy. It is required to see things around us. A source of light is an object which gives out light. All the sources of light can be divided into two groups – natural sources of light and man-made sources of light.

The sources of light which occur in nature as such are called natural sources of light. Example – sun and stars.

The sources of light which have been made by man are called man-made sources of light. Example – electric bulb, tube-light, torch, etc.
