Briefly explain resonance frequency and one common misconception about it.

## Resonance Frequency **Resonance frequency** is the natural frequency at which a system vibrates most easily and with maximum amplitude when disturbed. When you apply a periodic force at this specific frequency, energy transfers most efficiently into the system, causing large oscillations even with relatively small inputs. Common examples include a child on a swing (push at the right rhythm and they go higher) or a wine glass shattering when exposed to a matching sound frequency. ## Common Misconception **Misconception:** "Resonance only occurs at exactly one precise frequency" **Reality:** While systems have a peak resonance frequency, they actually respond to a *range* of frequencies around this peak. The response is strongest at the resonance frequency but gradually decreases at nearby frequencies. The width of this response range depends on damping—systems with low damping (like a tuning fork) have sharp, narrow resonance peaks, while heavily damped systems (like a car's shock absorbers) have broad, gentle peaks. This is why you don't need to push a swing at an impossibly exact rhythm for it to work.
