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 * [tex]\Delta[/tex]x/[tex]\lambda[/tex]+ 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

help please?

thr is no restriction on m..so you can simply choose it by urslf..
well i took it 1...
for part one...simple clue...
distance between two speakers shud be integer multiple of lambda...
so in one case take it m and in 2nd take it (m+1)...
