What is an Atomic Clock?
An atomic clock is a highly sophisticated timekeeping device that uses the vibrations of atoms to measure time with extraordinary precision. Unlike traditional clocks that rely on mechanical or quartz movements, atomic clocks operate based on the natural frequency of atoms, typically cesium or rubidium. These atoms oscillate at a consistent frequency when exposed to microwave radiation, allowing for incredibly accurate time measurement.
You might be surprised to learn that atomic clocks are so precise that they can lose or gain only about one second over millions of years.
