Two sources of sound are in resonance when

Two radio frequency sources S_(1) and S_(2) , separated by distance 2.5 m emitting in phase waves of wavelength 1m. A detector moves in a large circular path around the two sources in a plane containing them. The number of maxima that will be detected by it over the complete circular path. are

What is the luminous flux of a source emitting radio waves ?

Two source of sound, S_(1) and S_(2) , emitting waves of equal wavelength 2 cm , are placed with a separation of 3 cm between them. A detector can be moved on a line parallel to S_(1) S_(2) and at a distance 24 cm from it. Initially, the detecor is equidistant from the two sources. Assuming that the waves emitted by the sources are in phase, find the minimum distance through which the detector should be shifted to detect a minimum of sound.
