Question

21. || Two loudspeakers in a 20°C room emit 686 Hz sound waves along the x-axis. a. If the speakers are in phase, what is the smallest distance between the speakers for which the interference of the sound waves is perfectly destructive? b. If the speakers are out of phase, what is the smallest distance between the speakers for which the interference of the sound waves is maximum constructive?
