A tube closed at one end and containing ...

A tube closed at one end and containing air produced, when excited the fundamental note of frequency `512 H_(Z)`. If the tube is opened at both ends, the fundamental frequency that can be exited is (in `H_(Z)`)
(a) `1024` (b) `512` (c ) `256` (d) `128`

A

1024

B

512

C

256

D

128

Text Solution

Verified by Experts

The correct Answer is:
A
`v=f_(1) lamda_(1)=f_(2)lamda_(2)rArr 512xx4L=f_(2)xx2L`
`rArr f_(2)=1024Hz`
