Two speakers, one at the origin and the other facing it at x = 1.04 m, are driven by the same oscillator at a frequency of 642 Hz. If the speed of sound is 343 m/s, find the following.
I know the wavelength is .53 m how do I do b?
(b) the location of a point of destructive interference closest to 0.520 m on the interval [0, 0.520 m]
