Answer:
The smallest separation distance between the speakers is 0.71 m.
Explanation:
Given that,
Two speakers, one directly behind the other, are each generating a 240-Hz sound wave, f = 240 Hz
Let the speed of sound is 343 m/s in air. The speed of sound is given by the formula as :
To produce destructive interference at a listener standing in front of them,
So, the smallest separation distance between the speakers is 0.71 m. Hence, this is the required solution.
