Atomic Clocks
Atomic clocks are highly precise timekeeping devices that use the vibrations of atoms to measure time. Specifically, they monitor the frequency of microwave radiation emitted or absorbed by atoms, usually cesium or rubidium, when they transition between energy levels. Because these atomic transitions occur at consistent rates, atomic clocks can keep time with incredible accuracy, often to within a billionth of a second over long periods. This precision makes them essential for global positioning systems (GPS), telecommunications, and scientific research, where exact timing is crucial.

Atomic clocks are highly precise timekeeping devices that use the vibrations of atoms—typically cesium or rubidium—to measure time. These atoms emit electromagnetic waves at a consistent frequency when they transition between energy states. Atomic clocks define the second based on these vibrations, making them far more accurate than traditional clocks. They can maintain time to within billionths of a second over long periods. Because of their precision, atomic clocks are essential for global positioning systems (GPS), telecommunications, and scientific research, ensuring that our technology remains synchronized and accurate.
