How Atomic Clocks Accurately Measure Time: The Science Explained

Discover how atomic clocks accurately measure time through atomic vibrations and precision technology.

168 views

Atomic clocks keep time by measuring the vibrations of atoms, typically cesium or rubidium. These atoms vibrate at a constant frequency when exposed to radiation, which is then used to regulate a clock's accuracy. This precision in tracking the vibrations ensures that atomic clocks maintain time with extreme accuracy, often losing just one second in millions of years.

FAQs & Answers

  1. What is an atomic clock? An atomic clock is a timekeeping device that uses the vibrations of atoms, such as cesium or rubidium, to maintain accurate time.
  2. How precise are atomic clocks? Atomic clocks are extremely precise, losing only one second over millions of years.
  3. What makes atomic clocks better than regular clocks? Atomic clocks offer unparalleled accuracy and stability due to their reliance on atomic vibrations rather than mechanical or quartz movements.
  4. How do atomic clocks work? Atomic clocks operate by measuring the frequency of microwave radiation emitted or absorbed by atoms as they transition between energy states.
