Question
In Fig 18-29, two loudspeakers, separated by a distance of 2.00 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of the listener, who is 3.75 m directly in front of one of the speakers. (a) For what frequencies in the audible range (20Hz to 20kHz) does the listener hear a minimum signal? (b) For what frequencies is the signal a maximum?

(a) For what frequencies in the audible range (20Hz to 20kHz) does the listener hear a minimum signal? (b) For what frequencies is the signal a maximum?Explanation / Answer
path difference x=(3.75^2-2^2) - 3.75
=0.5m
if this path differece is =n maximum sound is heared
if =(2n+1) minimum sound is heard we require to find frequency
