A jolt of energy - in the form of microwaves - may cause an electron to increase to a higher orbit across the nucleus. The electron must get exactly the appropriate amount of Power - meaning the microwaves have to have an exceedingly certain frequency - so that you can make this soar. The Vitality necessary to make electrons transform orbits is unique in each ingredient and dependable all through the universe for all atoms of the presented aspect. For example, the frequency necessary to make electrons in the carbon atom transform Electricity amounts is similar For each carbon atom within the universe. The Deep Area Atomic Clock employs mercury atoms; a distinct frequency is necessary to create Individuals electrons adjust stages, and that frequency might be steady for all mercury atoms. "The point that the Power difference between these orbits is such a precise and steady benefit is really The crucial element ingredient for atomic clocks," mentioned Eric Burt, an atomic clock physicist at JPL.
