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 P_{0} where the microphone is equidistant from the two speakers. As we move the microphone away from P_{0} 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 here

** Part (a) ** What is the distance, in meters, between *P*_{0} and the first intensity maximum?

|*y*_{1}| =?

**Part (b) ** What is the distance, in meters, between *P*_{0} and the second intensity minimum?

|*y*‘_{2}| = ?

**Part (c) ** What is the distance, in meters, between P_{0} and the second intensity maximum?

|*y*_{2}| =?

**Part (d) ** What is the distance, in meters, between P_{0} and the third intensity minimum?

|*y*‘_{3}| =?
