A clock helps us measure time, but there are various types. The clocks we commonly use, like wristwatches or wall clocks, work with repetitive mechanisms, such as a swinging pendulum or a vibrating crystal. These movements make clock hands move and tell us the time. Today, atomic clocks, which use hydrogen or cesium atoms, are the globally accepted method for measuring time.
