About Atomic Clock:
- It is a highly precise timekeeping device based on the vibrations of atoms, usually components like Cs-133 are used to quantify time.
- Widely used in scientific research, telecommunications, navigation systems (GPS), and space exploration.
- It works by detecting the frequency of electromagnetic radiation that the atoms absorb or release when they change energy levels.
- The duration of a second is determined by the resonance frequency of these transitions.
Advantages of Atomic Clocks:
- Extremely reliable, gaining or losing only a second over millions of years.
- Enhances GPS precision for accurate positioning and navigation.
- Essential for experiments needing precise time measurements, like testing relativity theories.
Why in the News?
- Recently, researchers have developed a portable optical Atomic Clock for shipboard use.
