Suppose that initially the speakers are side by side, a few centimeters apart, equidistant from a listener 2.18 m in front of the speakers.
a)One of the speakers is slowly moved straight back away from the listener until at some point she hears almost no sound. How far is the speaker moved?
(b) How much farther back should the speaker be moved for the sound to be about as loud as it was initially?Answer QuestionBe the first to answer this question.
