Question
Two speakers, one directly behind the other, are each generating a 375-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed of sound to be 341 m/s.
Two speakers, one directly behind the other, are each generating a 375-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed of sound to be 341 m/s.Explanation / Answer
Wavelength is 341/375 = 1.09 meters destructive means 180º out of phase, so the spacing would be half the above or 0.504 meters
