Question

take 4 identical bowls and fill different amount of water in each. Tap each with a spoon and observe the variation of sound​

Answer 1

Answer:

With our musical water bowls, when there is more water in the bowl, the pitch of the soundproduced is lower because the water has caused the bowl to vibrate slower. When there is a smaller amount of water in the bowl the pitch is higher because the bowl is vibrating faster.
