Resonance

Resonance is like a game of musical chairs. Imagine a room full of chairs and people. When the music starts, everyone walks around the room while they listen to the music. After a while, the music stops and everyone finds a chair to sit in. When the right chair is found, it's as if the music and chair match perfectly together. That perfect match is called resonance. The same idea can be applied to things like sound waves and vibrations. When something matches up perfectly with a vibration or sound wave, it's called resonance.
