What is atomic time clock?

What is atomic time clock?

atomic clock, type of clock that uses certain resonance frequencies of atoms (usually cesium or rubidium) to keep time with extreme accuracy. The electronic components of atomic clocks are regulated by the frequency of the microwave electromagnetic radiation.

Are atomic clocks real?

In February 2022, scientists at the University of Wisconsin-Madison reported an optical atomic clock with an accuracy of losing a second in 300 billion years.

What is an atomic clock and how does it work?

In an atomic clock, the frequency of the quartz oscillator is transformed into a frequency that is applied to a collection of atoms. If the derived frequency is correct, it will cause many electrons in the atoms to change energy levels. If the frequency is incorrect, far fewer electrons will jump.

Who invented atomic clock?
