The intensities of two sources are`I`a nd `9I` respectively,If the phase difference between the waves emitted by then is `pi`then the resultant intensity at the point of observation will be-

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

For minimum intensity the phase difference between the two waves is

The intensity of interference waves in an interference pattern is same as I_(0) . The resultant intensity at the point of observation will be

The intensity of interference waves in an interference pattern is same as I_(0) . The resultant intensity at any point of observation will be

Two light sources with intensity I_(0) each interfere in a medium where phase difference between them us (pi)/2 . Resultant intensity at the point would be.

Two light sources with intensity I_(0) each interfere in a medium where phase difference between them us (pi)/2 . Resultant intensity at the point would be.

Two coherent sources each emitting light of intensity I_(0) Interfere, in a medium at a point, where phase different between them is (2pi)/3 . Then, the resultant intensity at that point would be.

Two coherent sources each emitting light of intensity I_(0) Interfere, in a medium at a point, where phase different between them is (2pi)/3 . Then, the resultant intensity at that point would be.
