Light waves of wavelength 5460 A, emitted by two coherent sources, meet at a point after travelling different paths. The path difference between the two wave trains at that point is 2.1 mum . then phase difference 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 .
