An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.43 m apart are powered by the same function generator producing sine waves at 1,248 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m?
