Kilohertz

The video tutorial explains the concept of Hertz, which is a unit of frequency measured in cycles per second. It further discusses how frequencies of phenomena like sound waves and radio waves are often expressed in kilohertz, providing a basic understanding of how these measurements are used in various contexts.
