In the realm of wireless communication, radio frequencies are designated in kilohertz (kHz), megahertz (MHz), and gigahertz (GHz). High-frequency sounds, including the chirping of birds or the hiss of cymbals, extend from 2,000 Hz up to 20,000 Hz, which represents the upper limit of human hearing.
How CPU Clock Speed Is Measured in Hertz
This fundamental metric applies to any event that repeats over time, although it is most commonly associated with waveforms such as sound, light, and radio signals. The Definition and Core Concept of Frequency At its core, frequency quantifies how often a repeating event occurs within a specific timeframe.
Electromagnetic Waves and Radio Signals Beyond sound, hertz are critical for measuring electromagnetic radiation, which includes visible light, radio waves, and X-rays. Human Auditory Range Understanding the frequency range of human hearing is crucial for fields like music production and acoustic engineering.

Medical and Scientific Uses. If a sound wave vibrates too slowly, it becomes a bass note; if it vibrates too quickly, it becomes a treble note.
