# Wave Interference and sound waves

## Homework Statement

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x= 0.540 m. If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x=0.950 m.

a: What is the frequency of the sound? Assume velocity of sound=340 m/s
b: What is the phase difference between the speakers?

## Homework Equations

The only equation I could relate to this would be the maximum constructive interference equation: 2pi * $$\Delta$$x/$$\lambda$$+ phase shift= m*2pi

## The Attempt at a Solution

I'm not sure what m would be or what value I would be solving for in part a
