Question
A hollow matallic 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 equilbrium 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.
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)]
