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, the tuning fork frequency is :
