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