Question

When we start filling an empty bucket with water from the tap, the pitch of the sound produced goes on changing. Why?

Solution

The pitch of the sound produced is determined by the length of the air column in the bucket.
The fundamental frequency of note emitted by one end closed pipe is given by,

straight v equals fraction numerator v over denominator 2 straight L end fraction

As the water fills the bucket, the length of the air column in the bucket goes on decreasing and as a result the pitch goes on increasing.
