Two turning forks of frequencies `n_(1)` and `n_(2)` produces n beats per second. If `n_(2)` and n are known, `n_(1)` may be given by

A

`n_(2)/n+n_(2)`

B

`n_(2)n`

C

`n_(2)pmn`

D

`n_(2)/n-n_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Beat frequency number of beats/sec.
`n=n_(2)-n_(1)orn_(1)-n_(2)thereforen_(1)=n_(2)pmn`
