Question:

Two loudspeakers are separated by a distance of 6 m. A listener sits directly in front of one speaker at a distance of 8 m so that the two speakers and the listener form a right triangle.

(a) Find the two lowest frequencies for which the path difference from the speakers to the listener is an odd number of half-wavelengths.

(b) Why can these frequencies be heard even if the speakers are driven in phase by the same amplifier?
