Fig, here shows P and Q as two equally intense coherent sources emitting radiations of wavelength 20m. The separation PQ is 5m, and phase of Q is ahead of the phase P by 90∘. A, B and C are three distant points of observation equidistant from the mid – point of PQ. The intensity of radiations of A, B, C will be in the ratio
