Assertion

Resonance is a special case of forced vibration in which the natural frequency of vibration of the body is the same as the impressed frequency of external periodic force and the amplitude of forced vibration is maximum.

Reason

The amplitude of forced vibrations of a body increases with an increase in the frequency of the externally impressed periodic force.
