Hertz

Hertz (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 Heinrich Rudolf Hertz, a German physicist who made significant contributions to the study of electromagnetism.

Definition

The hertz is defined as one cycle per second. The term cycle refers to the complete oscillation of a wave from its starting point, through its highest and lowest points, and back to its starting point. In the context of waves and vibrations, a cycle is a single complete oscillation.

Applications

Hertz is used in many areas of science and technology. In physics, it is used to measure wave frequencies, such as sound waves, light waves, and radio waves. In electronics, it is used to measure the frequency of alternating current and the clock speed of computers. In music, it is used to define the pitch of musical notes.

History

The hertz was named in honor of Heinrich Rudolf Hertz, a German physicist who was the first to conclusively prove the existence of electromagnetic waves. His experiments with these waves laid the foundation for the invention of radio.
