What is resonance?
Quick Answer
Resonance happens when a system is driven at or near its natural frequency, causing large-amplitude vibrations or oscillations. It can be useful or destructive.
The Full Story
Resonance occurs when repeated pushes or waves match an object’s natural frequency, making it respond strongly. A child on a swing goes higher when pushed at the right rhythm, and a glass can sometimes vibrate strongly at the right sound frequency. Bridges, buildings, and engines must be designed to avoid dangerous resonance. In physics, resonance is also important in atoms, molecules, radio circuits, and nuclear magnetic resonance.
