Resonance can be looked at as forced vibration with the
A) least amount of energy input.B) maximum amount of energy input.C) matching of wave amplitudes.D) matching of constructive and destructive interference.E) minimum beat frequency.

Resonance is caused when a periodic motion is supported by an external periodic force. In resonance, frequency of periodic motion and frequency of external periodic motion becomes equal. In this case there is maximum absorption of energy by the system. Take the case of a boy who is enjoying a ride on a swing which is supported by an external periodic pushing from behind, resulting in swing motion with maximum amplitude. .
