Figure shows two isotropic point sources of sound, S1 and S2. The sources emit waves in phase at wavelength 0.50 m; they are separated by D = 1.75 m. If we move a sound detector along a large circle centered at the midpoint between the sources, at how many points do waves arrive at the detector(a) Exactly in phase and(b) Exactly out ofphase?
