Question

what is principle of cesium atomic clock

Answer 1

Until the 1990s the cesium beam atomic clock was the most accurate standard of atomic time and frequency. The principle underlying the cesium clock is that all atoms of cesium-133 are identical and, when they absorb or release energy, produce radiation of exactly the same frequency, which makes the atoms perfect timepiece.

Answer 2

Explanation:

The major difference is associated with the element used and the means of detecting when the energy level changes. The first type of atomic clock is the cesium atomic clock. For this type of atomic clock, it employs a beam of cesium atoms. The clock separates cesium atoms of different energy levels by magnetic field.
