A tube, closed at one end and containing air, produces, when excited, the fundamental note of frequency `512 Hz`. If the tube is open at both ands the fundamental frequency that can be excited is (in Hz)

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`
