Two independent sources of light will not produce steady interference pattern because

If two coherent light waves produce minima of fifth order, the path difference between the waves is-

Assertion (A): For best contrast between maxima and minima in the interference pattern of Young's double slit experiment, the amplitudes of light waves emerging from the two sources should be equal. Reason (R): For interference, the sources must be coherent.

Two sources are called coherent if they produce waves

Two sources are called coherent if they produce waves

Statement-1: Two separate sources of light giving out light of the same frequency do not produce sustained interference. Statement-2 : The amplitude of the waves from the sources are never equal.

Light waves from two coherent sources having intensities I and 2I cross each other at a point with a phase difference of 60^(@) . The intensity at the point will be

Two sources of waves are called coherent if

It is found that what waves of same intensity from two coherent sources superpose at a certain point, then the resultant intensity is equal to the intensity of one wave only. This means that the phase difference between the two waves at that point is
