Question

take some musical instruments fill up water in them on different level and observe the sound produced​

Answer 1

Answer:

Each of the bowls will have a different tone when hit with the wooden rod, the bowl with the most water will have the highest pitch while the bowl with the least water will have the lowest pitch. Small vibrations are made when you hit the bowl and this creates sound waves which travel through the water. Less water means faster vibrations, a lower frequency, that is lowest pitch.

Hence, when struck with a wooden rod, the bowl d will produce the sound of the lowest pitch.
