rubidium atomic clock

A rubidium atomic clock is a highly precise timekeeping device that uses the vibrations of rubidium atoms to measure time accurately. It works by passing a microwave signal through a rubidium vapor; the atoms resonate at a very specific frequency. When the microwave frequency matches this natural frequency, the atoms absorb energy, signaling the clock to adjust and maintain precise timing. These clocks are crucial for GPS navigation, telecommunications, and scientific research because they provide extremely stable and accurate time measurements over long periods.
