Homework Help: physics

Posted by sarah on Wednesday, November 10, 2010 at 9:02am.

Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. The frequency of the waves emitted by each speaker is 172 \rm Hz. You are 8.00 \rm m from speaker A. Take the speed of sound in air to be 344 \rm m/s.

What is the closest you can be to speaker B and be at a point of destructive interference?
