Required information
Two speakers vibrate in phase with each other at 523 Hz. At certain points in the room, the sound waves from the two
speakers interfere destructively. One such point is 1.45 m from speaker #1 and is between 2.00 m and 4.00 m from
speaker #2. The speed of sound in air is 343 m/s.
How far is this point from speaker #2?
