Question
Why does an empty vessel produce more sound than the filled vessel?
Solution
The intensity of sound is directly proportional to the square of amplitude of vibration.
When empty vessel is struck, the air molecules are set in vibration and when filled vessel is struck the liquid molecules are set in vibration.
Since, the amplitude of vibration of air molecules is greater than liquid molecules, therefore empty vessel produces louder sound than the filled vessel.
