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 \(x = 0.50 \text{ m}\). If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at \(x = 0.90 \text{ m}\). a. What is the frequency of the sound? Assume \(v_{\text{sound}} = 340 \text{ m/s}\). b. What is the phase difference between the speakers?
