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 :-

A

`(V+ upsilon)/(4(L + l))`

B

`(V + upsilon)/(4(L-l))`

C

`(V - upsilon)/(4(L-l))`

D

`(V - upsilon)/(4(L + l))`

A metre long tube open at one end with a movable piston at the other end, shows resonance with a fixed frequency source ( a tuning fork of frequency 340Hz) when the tube length is 0.255m or 0.793m. Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected.
