Two loudspeakers A and B (connected to the same source) are 20.0 m apart and each produce a sound wave of frequency 220 Hz. You can assume that the waves produced by the speakers are in phase. A microphone is initially placed at the midpoint (O) of the line AB. The microphone is then moved along AB from O towards B. What is the shortest distance the microphone must be moved until the sound intensity detected by it is a maximum? [Speed of sound = 340 m/s] 7.50m
