Imagine a clock that counts every little beat like a drummer counting beats in a song. Some clocks use pendulums or gears to count time, but the most precise ones use something even smaller: atoms! These tiny particles vibrate at very steady rates, helping the clock keep perfect time. Just like how you can tell when your favorite song is over because it has the same number of beats every time.
Examples
- A grandfather clock uses a pendulum that swings back and forth to count seconds.
- Your phone’s clock uses tiny vibrations inside the phone to keep time precise.
- Scientists use atoms that vibrate like perfect metronomes to measure time exactly.
