. On keeping the stem of a vibrating tuning fork on the surface of a table, a loud sound is heard. Give reason

Best Answer

A loud sound is heard only when a special case of forced vibration (resonance) has occurred.

When the frequency of the periodic force applied on a body is equal to the natural frequency of that body, we hear a loud sound called resonance.

It is due to resonance that a loud sound is heard on keeping the stem of a vibrating tuning fork on the surface of a table.
