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.
