Answer 2

A group of light rays given out from a source is BEAM OF LIGHT.

• Beam of light is a group of light rays projected from a source along a particular direction.

• Beam of light is helpful is understanding the concept of RECTILINEAR PROPAGATION OF LIGHT.

• Frankly speaking, in reality, a single ray of light is not possible , rather beam of light is more practical.

• Beam of light can be classified as :

1. Parallel beams
2. Convergent beams
3. Divergent beams

• Whenever we see any source of light around us (e.g. sun, tubelight , filament bulb), these all emit a beam of light instead of a ray of light.
