Answer:
57.17 Hz 114.34 Hz 285 Hz
Explanation:
The distance between the men and 1 speaker = 3.5 m
Distance between the men and second speaker = 10-3.5= 6.5 m
Here at this point there will be no sound so there will be destructive interference
Path difference
We know that for destructive interference
here v is the speed of sound in air
So for m =0
for m =1
for m=2
Answer:
False
