- 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? marrow_forwarda) Consider the following function, where A is a constant. y(x,t) = A(x — vt). Can this represent a wave that travels along?
