Two sinusoidal plane waves of same frequency having intensities I_(0) and 4I_(0) are travelling in the same direction. The resultant intensity at a point at which waves meet with a phase difference of zero radian is

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)
