Source Of Light And Natural Light

Debraj Paul
11/02/2017 0 0

Any object which has an ability of producing light energy at its own is called as the source of light. e.g., Sun, Firefly, Battery, Cell Candle, Bulb etc.

Natural light

Our main source of natural light is the sun. The sun is a star that is a huge ball of gas. Explosions at the centre of the sun produce large amounts of energy. This energy is released as light and heat. Some of this light reaches Earth and gives us daylight. The light that comes from the sun is known as white light.

Other forms of natural light include the moon and the stars. The stars provide only small amounts of light at night as they are billions of kilometres away from Earth. A full moon, however, can provide quite a lot of light. The light from the moon is just light reflected from the sun.
