(C) For a closed pipe (vessel),the fundamental frequency $n$ is given by $n = \frac{v}{4l}$,where $v$ is the speed of sound and $l$ is the length of the air column.From the formula,we can see that $n \propto \frac{1}{l}$.When the vessel is partially filled with water,the length of the air column $l$ decreases.Since the frequency $n$ is inversely proportional to the length $l$,a decrease in $l$ leads to an increase in the frequency $n$.Therefore,the frequency of vibration of the air column increases.

An empty vessel is partially filled with water. What happens to the frequency of vibration of the air column in the vessel?
