    An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms where each atom that is used has naturally occurring oscillations. For any clock to function efficiently, oscillations produce a steady reproducible beat regularly. Clocks for displaying time predominantly use a quartz crystal that produces a low frequency (32,767 Hz)…
