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. The closer the frequency is to the inherent oscillation frequency of the atoms, the more atom… WebMar 28, 2024 · As a clock pendulum swings back and forth, and a tuning-fork-shaped piece of quartz oscillates with an electric current in a watch, you count the periodic swings of electrons in an atomic...
