Question

Write two conductions for two optical sources to become coherent sources.

Answer 1

two coherent light sources are produced by splitting a single light source

conductivity

A measure of how easily an electric current can pass through a material. The conductivity is the reciprocal of the resistance. The SI unit of conductance is the siemens.

Answer 2

Explanation:

Coherent sources: Two sources are said to be coherent in nature if they emit light of same frequency and of a stable path difference.

Conditions for sustained interference pattern:

The two sources of light must be coherent with same frequency or wavelength and with same phase or constant phase difference.
