Two radio stations broadcast their programmes at the same amplitude A and at slightly different frequencies omega_(1) and omega_(2) respectively, where omega_(1) - omega_(2) = 10^(3) Hz . A detector receives the signals from the two stations simultaneously, it can only detect signals of intensity ge 2A^(2) . (i) Find the time interval between successive maxima of the intensity of the signal received by the detector. (ii) Find the time for which the detector remains idle in each cycle of the intensity of the signal.
