Answer is:
same frequency and with a constant phase relationship
Explanation:
Two sources of light are coherent if they have same frequency and with a constant phase relationship
Answer is:
the sources are coherent
Explanation:
Interference effects of light from two sources can be observed if the sources are coherent
Answer is:
An integral multiple of wavelength
Explanation:
If we have two coherent sources 'S1 and S2' vibrating in phase, then for an arbitrary point P constructive interference is observed whenever the path difference is integral multiple of wavelength.
