The resonance condition occurs when the following conditions are met:
1. The amplitude of oscillation is minimum.
2. The driving frequency of the external force is equal to the velocity of the oscillator.
3. The angular frequency of the oscillator corresponds to the maximum velocity of the oscillator.
4. The angular frequency of the oscillator is equal to the frequency of the external applied force.
5. The displacement of oscillation becomes maximum, but the velocity becomes minimum.
