Alistener is sitting somewhere on the line between two loudspeakers that are 10 m apart. the speakers are each emitting a sine wave with the same frequency and no initial phase difference. the listener finds that the sound is completely cancelled when he is at a distance of 3.5 m from one of the speakers. what is a possible frequency of the sound?

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

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt
