_{Definition of Hertz (Hz):}

1. Hertz (Hz) is the standard unit of frequency in the International System of Units (SI).
2. Frequency refers to the number of cycles or repetitions of a wave that occur in one second.
3. Hertz measures the number of oscillations, vibrations, or waves per second.
4. One Hertz is equivalent to one cycle per second, commonly denoted as “1 Hz.”
5. Hertz is commonly used to measure the frequency of various phenomena, including electromagnetic waves, sound waves, alternating currents, and radio waves.
6. Hertz is named after Heinrich Hertz, a German physicist who made significant contributions to the study of electromagnetism in the late 19th century.
7. Hertz is also used in telecommunications to indicate the frequency of analog and digital signals, providing information about their transmission rate or bandwidth.
