A closed organ pipe and an open organ pipe have their first overtones identical in frequency . Their lenghts are in the ratio

A

`1:2`

B

`2:3`

C

`3:4`

D

`4:5`

Text Solution

Verified by Experts

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