So the frequency of an oscillator is always the same as the frequency of the force, if that force is a sinusoidal function of time. What's the best way to visualize why this is so? And also, why is the frequency of the oscillator in phase with the force if the force is below the resonance frequency of the oscillator, but 180 degrees out of phase with it if the frequency of the force is above the resonance frequency?
If the force has a constant frequency, but is not sinusoidal, does the oscillator also end up with that same frequency?
