WebTime standards [ edit] An atomic clock is based on a system of atoms which may be in one of two possible energy states. A group of atoms in one state is prepared, then subjected to microwave radiation. If the radiation is of the correct frequency, a number of atoms will transition to the other energy state. Web18 de jan. de 2024 · Today, one second is defined as “9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom”. That’s a mouthful. That number seems random because each and every definition of a second has by necessity been based on the one that came before.
