Two small stereo speakers are 2.8 m apart and act as a double-slit interference experiment by sound waves. If the opposite wall of the room is 7.5 m away and the sound frequency is 1.4 kHz, what is the distance among the two interference maxima nearest the center of the wall? Suppose the speakers act as point sources of sound.
