A pair of speakers separated by 0.700m are driven by the same oscillator at a frequency of 658 Hz. An observer, originally positioned at one of the speakers, begins to walk along a line perpendicular to the line joining the speakers. (Assume the speed of sound is 345 m/s.)

a) How far must the observer walk before reaching arelative maximum in intensity?
b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity?
