Two tuning forks `A and B` are sounded together and `8 beats//s` are heard . `A` is in resonance with a column of air `32 cm` long in a pipe closed at one end and `B` is increased by one `cm`. Calculate the frequency of fork .

A

`264Hz`, `256Hz`

B

`272Hz`, `264Hz`

C

`231Hz`, `224Hz`

D

`220Hz`, `512Hz`

Text Solution

Verified by Experts

The correct Answer is:
C
`(n_(1))/(n_(2))=(l_(2))/(l_(1))=(33)/(32)` and `n_(1)-n_(2)=7`
