First, we use the wave equation to determine the wavelength of the sound produced by the speakers:

c = f*l

where c is the speed of sound, f is the frequency, and l is the wavelength. Re-arranging gives us:

l = c/f = (330 m/s)/(200 Hz) = 1.65 m

At the listener's location, the cycle of the wave is determined by the distance from the speaker divided ...
