Question

Write about coherent sources???❤❤

Answer 1

$here \: is \: your \: answer$


☆coherent sources :--
===================

★sources emitting waves of same frequency or wavelength having either a zero or a constant phase difference are called coherent sources.

it may be noted that two independent sources do not fulfil the requirement of constant phase difference. therefore such sources cannot be used to produce interference pattern. these sources are produced by division of wave front.

Answer 2

heya mate

The answer of ur question is

♢ Coherent sources are those sources which have same frequency , and also may have zero or constant phase difference.

♢These sources are produced by division of wave front.

♢ For ex - lamp , sun , tubelight etc are example of this
