Two loudspeakers are placed 3.00 m apart, as shown in the figure. They emit 450 Hz sounds, in phase. A microphone is placed d = 3.00 m distant from a point midway among the two speakers, where an intensity maximum is recorded. (a) How far should the microphone be moved to the right to find the first intensity minimum? 1 m (b) Assume the speakers are reconnected so that the 450 Hz sounds they emit are precisely out of phase. At what positions (how far should the microphone be moved to the right) are the intensity minimum and maximum now? 2 m (minimum) 3 m (maximum)
