Question

Two speakers face each other, and they each emit a sound of wavelength . One speaker is 180 out of phase with respect to the other. If we separate the speakers by a distance 1.5, 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. Select all that apply. Two speakers face each other, and they each emit a sound of wavelength . One speaker is 180 out of phase with respect to the other.

Select all that apply. A) 1/4 lambda B) 1/2 lambda C) 3/4 lambda D) lambda E)0 lambda 0

Explanation / Answer

One speaker is 180* out of phase with other
distance between speakers = 1.5

Let the angle be = tan^(-1) (1.5) 56.30*

For maxima = Lambda
