A closed pipe is suddenly opened and changed to an open pipe of same length . The fundamental frequency of the resulting open pipe is less than that of `3rd` hoarmonic of the earlier closed pipe by `55Hz`. Then , the value of fundamental frequency of the closed pipe is

A

`165Hz`

B

`100Hz`

C

`55Hz`

D

`220Hz`

Text Solution

Verified by Experts

The correct Answer is:
C
`(n_(C1))/(n_(03))=(3)/(2)impliesn_(C1)=(3)/(2)n_(03)n_(C1)=n_(03)-55`
