A cylinder resonance tube open at both ends has fundamental frequency `F` in air. Half of the length of the tube is dipped vertically in water. The fundamental frequency to the air column now is …………………… .

Text Solution

Verified by Experts

In figure (i)

`(lamda)/(2)=1implies lamda=21`
`f=(c)/(lamda)=(c)/(21)`
In figure (ii),
`(lamda')/(2)=(1)/(2)implies'=21`
From figure (ii) and (i), `f'=(c)/(lamda')=(c)/(21)=f`
