Question

A hollow metallic tube of length L and closed at one end produce resonance with a tuning fork of frequency n. The entire tube is then heated carefully so that at equilibrium temperature its length changes by l. If the change in velocity V of sound is v, the resonance will now produced by tuning fork of frequency : -

Options

A.(V + v) / (4(L + l))
B.(V + v) / (4(L - l))
C.(V - v) / (4(L + l))
D.(V - v) / (4(L - l))

Solution

For closed tube
= L and L + l f′ =
