7. A pair of speakers separated by .7 meters are playing the same tone with a frequency of 690 Hertz. An observer originally positioned at one of the speakers begins to walk along a line perpendicular to the line joining the speakers. The speed of sound in the air is 345 m/s. a. How far must the observer walk before reaching a relative maximum in intensity? b. How far must the observer walk before reaching a relative minimum in intensity?
