Question

Two speakers face each other, and they each emit a sound of wavelength %u03BB. One speaker is 180%u2218 out of phase with respect to the other. If we separate the speakers by a distance 1.5%u03BB, how far from the left-most speaker should we place a microphone in order to pick up the loudest sound? Ignore reflections from nearby surfaces.
