If two sources have a randomly varying phase difference f(t), the resultant intensity will be given by:

The intensities of two light sources are I and 91 .If the phase difference between the waves is pi then resultant intensity will be :-

Assertion: Two identical waves due to two coherent sources interfere at a point with a phase difference of (2pi)/3 , then the resultant intensity at this point is equal to the individual intensity of the sources. Reason: A phase difference of (2pi)/3 is equivalent to a path difference of lambda/3 .

Assertion: Two identical waves due to two coherent sources interfere at a point with a phase difference of (2pi)/3 , then the resultant intensity at this point is equal to the individual intensity of the sources. Reason: A phase difference of (2pi)/3 is equivalent to a path difference of lambda/3 .

When two waves of intensities l_1 and l_2 coming from coherent sources interfere at a point P, where phase difference is phi , then resultant intensity (l_(res)) at point P would be

When two waves of intensities l_1 and l_2 coming from coherent sources interfere at a point P, where phase difference is phi , then resultant intensity (l_(res)) at point P would be

Light waves from two coherent sources having intensities I and 2I cross each other at a point with a phase difference of 60°. What is the resultant intensity at the point?
