Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.550 meter. If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x = 0.940 meter.
Determine what is the frequency of the sound? Assume vsound = 340m/s.
Calculate the phase difference between the speakers?
