If two light waves each of amplitude a travelling a travelling through a medium arrive at a point in opposite phase then the resultant amplitude R at that points is

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: Three waves of equal amplitudes interfere at a point. Phase difference between two successive waves is pi/2 . Then, resultant intensity is same as the intensity due to individual wave. Reason: Two different light sources are never coherent.
