An effect analogous to two-slit interference can occur with sound waves, instead of light. in an open field, two speakers placed 1.30 m apart are powered by a single function generator producing sine waves at 1200-hz frequency. a student walks along a line 12.5 m away and parallel to the line between the speakers. she hears an alternating pattern of loud and quiet, due to constructive and destructive interference. what is : (a) the wavelength of this sound and (b) the distance between the central maximum and the first maximum (loud) position along this line
