P and Q as two equally intense coherent sources emitting

Last updated: 6/30/2023

P and Q as two equally intense coherent sources emitting radiations of wavelength 20m as shown in the figure The separation PQ is 5m and phase of P is ahead of the phase of Q by 900 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 the ratio B C 1 0 1 4 PQ A
