When two sound sources of the same amplitude but of slightly different frequencies `v_(1)` and `v_(2)` are sounded simultaneously, the sound one hears has a frequency equal to

A

`abs(upsilon_(1)-upsilon_(2))`

B

`abs((upsilon_(1)-upsilon_(2))/2)`

C

`sqrt(upsilon_(1)upsilon_(2))`

D

`abs(upsilon_(1)+upsilon_(2))`

Text Solution

Verified by Experts

The correct Answer is:
B

The resulting sound wave has a frequency equal to half the sum of the individual frequencies. Note that the resulting intensity varies at the beat frequency equal to difference of the individual frequencies.
