Point sources and extened sources of light

Answers

Answered by aayan0143

A point source is really a mathematical construct. It is a point singularity of emission on a source. Point sources emit spherical waves of radiation. The surface of constant phase of light from the point source is called a wavefront. In other words, a wavefront is a surface of constant spatial phase. Extended sources are made up of a collection of such point sources

The sources of light from which few rays come are called point source of light.

Those source of light from which many rays come are called extended source of light.
