1.	1) What is light? 2) What is source of light? 3) How do you classify the light sources? 4) What are the different types of light beams? Explain.
Answer» 1) Light is a form of energy. 2) Light energy releases from different objects called sources of light. 3) Sources which release light energy on their own are called natural sources. Ex: sun, stars. Sources which need the human involvement to release light energy are called manmade sources of light. Ex: torch light, candle, bulb etc. 4) Actually, light is not a single ray, but a bundle of rays. This bundle of light rays are called beam of light rays. These are three types : i. Parallel beam of light rays : Light rays which travel parallel to each other are called Parallel beam of light rays. ii. Converging beam of light rays : “Light rays which travel from different directions to meet at a point are called as Converging beam of light rays”. iii. Diverging beam of light rays : “Light rays which travel from a source moving in different’ directions are called as Diverging beam of light rays.”

Answer»

1) Light is a form of energy.

2) Light energy releases from different objects called sources of light.

3) Sources which release light energy on their own are called natural sources.

Ex: sun, stars.

Sources which need the human involvement to release light energy are called manmade sources of light.

Ex: torch light, candle, bulb etc.

4) Actually, light is not a single ray, but a bundle of rays. This bundle of light rays are called beam of light rays.

These are three types :

i. Parallel beam of light rays :

Light rays which travel parallel to each other are called Parallel beam of light rays.

ii. Converging beam of light rays :

“Light rays which travel from different directions to meet at a point are called as Converging beam of light rays”.

iii. Diverging beam of light rays :

“Light rays which travel from a source moving in different’ directions are called as Diverging beam of light rays.”
