14 A tuning fork vibrating at frequency 800 Hz produces resonance in a resonance column tube The upper end is open and the lower end is closed by the water surface which can be varied Successive resonances are observed at lengths 9 75 cm 31 25 cm and 52 75 cm Calculate the speed of sound in air from these data nu Solution For the tube open at one end the resonance frequencies are where n is a positive odd integer If the tuning fork has a frequency v and l l l are the successive lengths of the tube in resonance with it we have nu 41 n 2 v 412 n 4 v 41 giving 13 12 1 1 1 2v 4v V V V 2v
