What exactly is a resonance frequency?

What exactly is a resonance frequency? I just want to understand what it is, I can solve for it but it's no use if I have no idea what it is.

Hi there,

Maybe a simple example would help you understand.

I believe you have already seen a swing. A device that you sit your kids into and push them back and forth. Ok, just to make sure. You probably noticed that the swing goes back and forth at a regular rythm. That's the resonance frequency. The natural frequency of the swing.

Now to make things a little complicated, you can take the swing with both hands and shake at any frequency. But if you rock it at its resonance frequency, you will see that with little effort you can increase it amplitude.

Hope this helps. Cheers

A resonance frequency is the natural frequency at which a system vibrates with maximum amplitude when subjected to a periodic force. This frequency is determined by the physical properties and geometry of the system and is independent of the amplitude of the periodic force. In simpler terms, it is the frequency at which an object or system naturally vibrates or oscillates when it is disturbed. This concept is important in many scientific fields, including physics, engineering, and music. In practical applications, understanding the resonance frequency of a system can help predict its behavior and avoid potential damage or failure.
