How far must they go or the observer be

0 like 0 dislike

A pair of speakers separated by distance d = 0.600 m are driven by the same oscillator at a frequency of 676 Hz. An observer originally positioned at one of the speakers begins to walk along a line perpendicular to the line joining the speakers as in the figure below. (Use v = 343 m/s.)

(a) How far must the observer walk before reaching a relative maximum in intensity? 

(b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity?
