In a resonance tube experiment when the tube is filled with water up to a height of 17.0 cm, from bottom, it resonates with a given tuning fork. When the water level is raised the next resonance with the same tuning fork occurs at a height of 24.5 cm. If the velocity of sound in air is 330 m s-1, the tuning fork frequency is :

Assume that the displacement s of air is proportional to the pressure difference Δp created by a sound wave. Displacement (s) further depends on the speed of sound (v), density of airρ and the frequency (f). If Δp=10 Pa, n=300 m s-1, p=1 kg m-3 and  f=1000 Hz, then s will be of the order of (take the multiplicative constant to be 1)
