What Is an Atomic Clock? NASA

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… WebJun 23, 2024 · One thing that wouldn’t exist without such accurate time is the Global Positioning System, or GPS.
