उत्तर
We should fill water in a beaker up to its brim. Now we should touch the surface of water with the prongs of a sound-making tuning fork that has been struck on a hard rubber pad earlier. The prongs of tuning fork that produces sound splashes water. This shows that the prongs of a sound-producing tuning fork are vibrating or rapidly traveling in forward and backward directions.
The prongs of a sound-producing tuning fork splash water, so they are vibrating.
