Description: An atomic clock is a precision clock that keeps time better than any other clock. The atomic clock helps in GPS navigation, Internet synchronization, and accurate identification of the position of the planets. The accuracy of an atomic clock depends on two factors, the first is the temperature of the sample atoms and the second is the frequency and intrinsic linewidth of the electronic or hyperfine transition. Higher frequencies and narrow lines increase precision. The cesium clock is the most accurate atomic clocks available today, and the countries that produce cesium clock in batches include the United States, Switzerland, Russia, and China. – PowerPoint PPT presentation
