Hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI). It is defined as one cycle per second. The unit is named after the German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetic waves.

Definition[edit | edit source]

One hertz represents one cycle per second. The SI unit is used to measure the frequency of periodic phenomena, such as sound waves, radio waves, and light waves. For example, a sound wave with a frequency of 50 Hz completes 50 cycles in one second.

History[edit | edit source]

The unit was established in honor of Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves. His experiments in the late 19th century confirmed the theories of James Clerk Maxwell.

Applications[edit | edit source]

Hertz is used in various fields, including:
