Two speakers are placed 4.5m apart, playing a coherent 660 hz tone. a listener is at a point 0.20 m from one speaker, on the line between the two speakers. the listener increases the frequency until the loudness they hear reaches a maximum. calculate the first frequency at which this occurs. take the speed of sound in air to be 344 ms-1.
