Question

What do you understand by a beam of light?

Answer 1

Drawing the diagram of the situation:

1. A bundle of light rays collectively is called a Beam of light.
2. Because light travels in a straight line and it is better to represent it with the help of a ray.
3. There are various types of beams of light which are as follows:

1. A parallel beam of light.
2. A convergent beam of light.
3. A divergent beam of light

A parallel beam of light: If all the light rays are not meeting at any point and are parallel to each other we call it a parallel beam of light.
A convergent beam of light: if a beam focuses at one point we call it a convergent beam of light.

A divergent beam of light: If a beam is moving and its area is increasing we can call it diverging.
