How Does Cesium Atom Clock Works
633 words 2 pages

Timekeeping is made possible due to the fact that the counting interval can be done repeatedly without high variation. Although mechanical means for example use of amechanical pendulum can be used in timekeeping, such methods are not as effective as theuse of atomic clock for time keeping. Although there are a number of elements that […]
