erpendicular to the line joining the speakers as in the figure below. (Use $v=343\mathrm{m}/\mathrm{s}$.) (a) How far must the observer walk before reaching a relative maximum in intensity? to minimize roundoff error. $\mathrm{m}$ (b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity? m
