Question

what do you mean by coherent sources​

Answer 1

Answer:

In physics, two wave sources are perfectly coherent if their frequency and waveform are identical and their phase difference is constant. Coherence is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference.

Answer 2

Answer:

In Physical, two wave sources are perfectly cohent if their frequency and wave form are identical and their phase different in constant. Coherence is an ideal property of waves that enables stationary ( i,.e. temporally and spatial constant ) inference.
