In the figure below, P and Q are two equally intense coherent sources emitting radiation of wavelength 20m. The separation between P and Q is 5m and the phase of P is ahead of that of Q by 90°.A,B and C are three distinct points of observation, each equidistant from the midpoint of PQ. The intensities of radiation at A,B,C will be in the ratio:
