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 4, 2024 · The Deep Space Atomic Clock is a sibling of the atomic clocks you interact with every day on your smart phone.
