A hollow metallic tube of length L and closed at one end produces 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 be produced by tuning fork of frequency,
