Two identical loudspeakers are located at (x1, y1) = (0, 0) and (x2, y2) = (2.5 m,−0.5 m). The loudspeakers are driven by separate amplifiers, so that the loudspeakers are out of phase with each other, and produce sound waves with frequency of 650 Hz. The ambient temperature of air is 37 0C. A small microphone is moved along the y-axis.

1. At what distances along the y-axis will there be constructive interference?

2. At what distances along the y-axis will there be destructive interference?

3. If, however, the microphone starts at the origin and is moving out to infinity at a rate of 10 m/s, what is the apparent frequency of the loudspeakers? How does this change the results from (a) and (b)? Explain.
