Question

what are the defination of parallel beam of light ,divergent beam of light and convergent beam of light

Answer 1

Parallel beam of light means the light rays are parallel to principal axis
convergent beam are ray which after reflection focus on a single point
Divergent beam are rays which after reflection diverges.

Answer 2

Answer:

$\sf \: parallel$

A beam of light is parallel when the rays of light are parallel to each other.

→The distance between the rays remains the same.

$\sf \: convergent$

→A beam of light is convergent when the rays of light meet at a point.

→The distance between the rays keeps decreasing till all the rays meet at a point.

$\sf \: divergent$

→A beam of light is divergent when the rays of light spread out from a point.

→The distance between the rays keeps increasing.
