An atomic clock is a reference clock whose operation is based on an atomic process, such as the frequency of electromagnetic radiation associated with a specific energy-level transition in an element such as caesium.
The Atomic Clock was invented in 1949, and is still used today.
1950s by Louis Essen.
The first atomic clock was invented in 1948 by the US Bureau of Standards.The first practical atomic clock was invented by English physicist Louis Essen in the 1955.Atomic clocks use the energy changes that take place in atoms to keep track of time. Atomic clocks are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.The most accurate, modern-day atomic clocks will neither lose nor gain a second in 168 million years.
Atomic clockThe U.S. atomic clock is the NIST-F1, it began to be used in 1999 and wont lose or gain a second in 20 million years. It is a fountain atomic clock that is made of a 3-foot vertical tube inside a taller structure. It uses lasers to cool cesium atoms, forming a ball of atoms that lasers then toss into the air, creating a fountain effect. This allows the atoms to be observed for a lot longer than could be done with any previous method.
The second atomic bomb was dropped in hiroshima.
Atomic Clock - album - was created in 2010.
The Atomic Clock was invented in 1949, and is still used today.

The wave button on an atomic clock is typically used to manually synchronize the clock with the atomic time signal broadcasted by radio transmitters. By pressing the wave button, the clock will attempt to receive the time signal and adjust its time accordingly for accuracy.
