How is it possible to detect the filling of a pitcher under a tap by hearing its sound at a distance?

उत्तर
As the water level in the pitcher increases, the length of the vibrating air column above the water surface decreases, and hence the frequency of the sound produced increases i.e., the sound gets shriller.
