Question

What type of wavefront will emerge from a (i) point source, and (ii) distance light source?

Answer 1

I. In case of a point source the wavefront is spherical in nature.

Ii. in case of a distant light source the wavefront is planer in nature.

Explanation:

• the wavefront of a wave depends on the type of the light source and the way in which the light source is propagated. It is useful in finding out the wave nature of the light and experiments on it.

• there is divergence of the light from the source outwards in case of a point source. Since it is liberated in all direction equally it is spherical in nature. However in case of a distant source it usually appears as a plain.
