Beam of light
A beam of light is a bunch of light rays. It may be convergent, divergent or parallel.
1. A convergent beam is that in which the rays are directed towards a point.
2. A divergent beam is that in which the rays are directed away from a point.
3. In a parallel beam of light all the rays are parallel to each other.
