In a resonance tube experiment when the tube is filled with water up to a height of $\displaystyle 17.0$ 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 $\displaystyle 24.5$ cm. If the velocity of sound in air is $\displaystyle 330 \mathrm{~m} / \mathrm{s}$, the tuning fork frequency is :
Official answer
(4)
$\displaystyle 2200$ Hz
