Question

How does an atomic clock work? How does it start telling extremely precise time?

In: Technology

Answer 1

An atomic uses a clump of atoms of a pure element. When excited, these atoms vibrate at a specific frequency that depends on the element’s electron alignments. By counting the vibrations, you can get a very precise clock that’s stable over a long time period.
