Why is it called atomic clock?
An atomic clock is the most accurate type of timepiece in the world, designed to measure time according to vibrations within atoms. NIST-F1, the United States’ standard atomic clock, is said to be so accurate that it would neither gain nor lose a second in over 30 million years.
What makes an atomic clock atomic?
An atomic clock is a clock that uses the resonance frequencies of atoms as its resonator. … The advantage of this approach is that atoms resonate at extremely consistent frequencies. If you take any atom of cesium and ask it to resonate, it will resonate at exactly the same frequency as any other atom of cesium.
Will an atomic clock set itself?
Atomic clocks set themselves and automatically adjust for daylight saving time (DST) to provide the most accurate timekeeping standard possible.
What is the most accurate atomic clock?
Today, the most precise clocks are based on a natural atomic resonance of the cesium atom—the atomic equivalent of a pendulum. For example, NIST-F1, one of the world’s most accurate time standards based on microwave atomic clocks, neither gains nor loses a second in 20 million years.
