Two speakers placed 0.99 m apart produce pure tones in sync with each other at a frequency of 1425 Hz. A microphone can be moved along a line parallel to the line joining the speakers and 8.2 m from it. An intensity maximum is measured a point P0 where the microphone is equidistant from the two speakers. As we move the microphone away from P0 to one side, we find intensity minima and maxima alternately. Take the speed of sound in air to be 344 m/s, and you can assume that the slits are close enough together that the equations that describe the interference pattern of light passing through two slits can be applied
