Question

Two loudspeakers are placed side by side a distance d = 4.00 m apart. A listener observes
maximum constructive interference while standing in front of the loudspeakers, equidistant from
both of them. The distance from the listener to the point halfway between the speakers is 1 =
5.00 m.
One of the loudspeakers is then moved directly away from the other. Once the speaker is moved
a distance r = 60.0 cm from its original position, the listener, who is not moving, observes
destructive interference for the first time.
Find the speed of sound in the air if both speakers emit a tone of frequency 700 Hz.

The two loudspeakers are sources of circular waves. The overlap of these waves causes interference. For simplicity, let us assume that these waves have equal amplitude.
