Understanding the Principle of Atomic Clocks
Learn how atomic clocks work by measuring atomic oscillations for precise timekeeping.
26 views
The principle of the atomic clock relies on the precise frequency of microwave radiation emitted or absorbed by atoms, typically cesium or rubidium. Atoms oscillate at a consistent frequency, and by measuring these oscillations, the atomic clock can keep extremely accurate time. This method provides a standard unit of time that underpins global timekeeping.
