Understanding the Physics of Atomic Clocks: How Do They Work?

Discover the science behind atomic clocks and learn how they measure time with unmatched precision through atomic vibrations.

0 views

Atomic clocks operate on the principle of measuring the vibration frequency of atoms, typically cesium or rubidium. These atoms oscillate at very precise intervals, aiding in timekeeping with exceptional accuracy. Cesium atomic clocks define the second as 9,192,631,770 cycles of radiation corresponding to the transition between two energy levels of the cesium atom. This precise measurement ensures that atomic clocks are incredibly stable and less prone to drift compared to traditional clocks.
