(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two Loud speakers are placed on a wall3.79 metersapart. A listener stands directly in front of one of the speakers,65.6 metersfrom the wall. The speakers are being driven by the same electric signal generated by a harmonic oscillator of frequency4010 HzThe speed of sound in Air is343 m/s. What is the phase difference[tex]\Delta\Phi[/tex]between the two waves? (answer in radians)

2. Relevant equations

y = A sin (kx (+/-) [tex]\omega[/tex]t

3. The attempt at a solution

I tried finding the wavelength and using trig to find the distance between the observer and speakers...but I'm not sure if it has anything to do with the problem, and I haven't gotten an answer out of this yet...I'm lost. The only thing I know is superposition, but I know that if you just add sin to sin, you don't just get sin, and I don't know how to derive that to see how that works....
