Question

Take a pot filled with water. Strike it lightly on its rim.

• What do you see?
• Why are waves formed on the water in the pot?

Answer 1

• When the rim of the pot is struck lightly, the pot starts vibrating and a sound is produced. At the same time, ripples or waves are seen on the surface of the water.
• The waves are formed because the vibrations of the pot are transferred to the water. These vibrations disturb the surface of the water and produce waves.

Thus, this activity shows that sound is produced by vibrations, and vibrations can also be transferred from one object to another.
