What is an Atomic Clock?
An
atomic clock is a timekeeping device that uses the vibrations of atoms, typically cesium or rubidium, to measure time with extreme precision. These vibrations are influenced by transitions between different energy levels within the atom, providing a highly stable frequency reference.
How Do Atomic Clocks Work?
Atomic clocks utilize the principle of atomic resonance. The most common type, the cesium atomic clock, operates by exposing cesium atoms to microwave radiation. When the radiation frequency matches the natural frequency of the cesium atoms, resonance occurs. This resonance is detected and used to control the clock's timekeeping mechanism.
