Two identical loudspeakers are located at (x1, y1) = (0, 0) and(x2, y2) = (2.5 m,−0.5 m). The loudspeakers are driven by separateamplifiers, so that the loudspeakers are out of phase with eachother, and produce sound waves with a frequency of 650 Hz. Theambient temperature of the air is 37C. A small microphone is movedalong the y-axis.
1. At what distances along the y-axis will there be constructiveinterference?
2. At what distances along the y-axis will there be destructiveinterference?
3. If, however, the microphone starts at the origin and ismoving out to infinity at a rate of 10 m/s, what is the apparentfrequency of the loudspeakers? How does this change the resultsfrom (a) and (b)? Explain.
