Two speakers vibrate in phase with one another at 523Hz. At certain points in the room, the sound waves from the two speakers interfere constructively. One such point is 2.28m from speaker #1 and is between 2m and 4m from speaker #2. How far is this point from speaker #2? Find all possible distances betweens 2m and 4m. The speed of sound in air is 343m/s. PLEASE HELP!
