Required Answer :-

: $\implies$ The property of any light source to measure a definite correlation between any two points with the same frequency and amplitude is known as the coherence of light and the light source is known as the coherent light source.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

There are two types of coherence depending on the position and time and are given by :

Temporal coherence

It is also known as longitudinal coherence. It is a type of coherence depending upon the time.It is a measure of the correlation of light waves phase at different directions of propagation.The temporal coherence has explained the monochromaticity of the light source.

Spatial coherence

It is a type of coherence depending upon the position.It is a measure of the correlation of the phase of the light wave at different transverse to the direction of propagation.The spatial coherence has explained the finite size of the light source.Additional information :- Incoherence refers to the phenomenon where two or more waves considered are out of phase or the correlation between the two points are not in phase with each other. The property of light sources such that there will be no correlation between the two emitted waves. All-natural and conventional sources of light are incoherent in nature. Incoherence explains the random motion of the emitted waves.
