Question

What do you mean by resonance? When does resonance occur?

✓

Answer

Resonance is a special case of forced vibration, when a body vibrates under the influence of an external periodic force, with a very large amplitude. Resonance occurs when the frequency of external force is either equal to or is integer multiple of the natural frequency of the vibrating body.
