The frequencies of sources A and B as shown in figure are same. The nature of interference at points P, Q and R will be if `AB = (lambda)/(2)` and the two sources are in same phase.

Consider two sources A and B as shown in the figure below . Let the two sources emit simple harmonic waves of same frequency but of different amplitudes , and both are in phase (same phase) . Let O be any point equidistant from A and B as shown in the figure . Calculate the intensity at points O , Y and X . ( X and Y are not equidistant from A & B)

What will happen to interference pattern if two sources of light are not in same phase ?

A : Light from two coherent sources is reaching the screen. If the path difference at a point on the screen for yellow light is 3lambda"/"2 , then the fringe at the point will be coloured. R : Two coherent sources always have same phase relationship at any point on the screen.

Two point coherent sources of power P_(0) and 4P_(0) emitting sound of frequency 150 Hz are kept at point A and B respectively. Both sources are in same phase. A detector is kept at point C as shown in figure. The distance of point A and B is r and 4r form detectro respectively. The speed of sound in medium is 300 m/s . Given P_(0)=64pi Watt and r=1m. The intensity observed by detector is
