If the frequency of first harmonic of a ...

If the frequency of first harmonic of a closed pipe is in unison with the third harmonic of an open pipe. Then, the ratio of lengths of the pipe closed at one end to the open at both the ends is

A

`1//12`

B

`3//4`

C

`1//6`

D

`6//7`

Text Solution

Verified by Experts

The correct Answer is:
C
`n_c = 3n_0`
`(v)/(4l_c) = 3xx(v)/(2l_0)`
`therefore l_c/l_0 = 1/6`
