The length of a given open end and close...

The length of a given open end and closed end pipes are `l_0 " and " l_c` respectively. If both the pipes emit same fundamental notes, then the ratio `l_0//l_c` is

A

`sqrt2:1`

B

`2:1`

C

`1:2`

D

`1:sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_0 = (v)/(2l_0) " and " n_c = (v)/(4l_c)`
`n_0/n_c = (v)/(2l_0) xx(4l_c)/(v) = (2l_c)/(l_0) therefore l_0/l_c = 2/1`
