A) \[{{v}_{o}}\]
B) \[2{{v}_{o}}\]
C) \[\frac{2}{3}{{v}_{o}}\]
D) \[\frac{3}{2}{{v}_{o}}\]
Correct Answer: B
Solution :
When open tube is dipped in water, it becomes a tube closed at one end. Fundamental frequency for open tube is \[{{v}_{o}}=\frac{v}{2l}\] Length available for resonance of closed tube is \[0.25\,\,l\]. \[\therefore \] \[{{v}_{c}}=\frac{v}{4(0.25\,l)}=\frac{v}{2l}\times 2=2{{v}_{o}}\]You need to login to perform this action.
