An oscillator is driven by a sinusoidal force. The frequency of the applied force:

must be equal to the natural frequency of the oscillator

must be greater than the natural frequency of the oscillator

must be less than the natural frequency of the oscillator

becomes the natural frequency of the oscillator

is independent of the natural frequency of the oscillator
