(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Constructive and destructive interefernec and a pair of speakers

1. The problem statement, all variables and given/known data

Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speakers emit sound waves that travel directly from the speaker to point Q

What is the lowest frequency for which constructive interference occurs at point ?

What is the lowest frequency for which destructive interference occurs at point ?

2. Relevant equations

not sure

3. The attempt at a solution

I know that constructive occurs when waves are in phase, destructive when 180 degrees/pi radians out of phase

Any ideas would be most appreciated

Thanks,

TFM
