Two identical forward-facing loudspeakers are 37.0 cm apart. They are both connected to a signal generator that makes them vibrate in phase at a frequency of 1.98 kHz. (Take the speed of sound as 340 m/s. Consider non-negative angles only). A. At what angles (in degrees), measured from the perpendicular bisector of the line joining the speakers, would a distant observer hear maximum sound intensity?
B. At what angles (in degrees) would such an observer hear minimum sound intensity?
