Hertz (Heinrich Hertz)

Hertz (Hz) is a unit of frequency that measures how many cycles or waves occur per second. Named after physicist Heinrich Hertz, it is used to quantify electromagnetic waves like radio, television, and cell signals. For example, a radio station broadcasting at 100 MHz (megahertz) transmits 100 million wave cycles each second. Understanding Hertz helps us grasp how fast signals oscillate and carry information through the air or cables. It’s a fundamental concept in wireless communication and physics, linking the frequency of wave phenomena to their behavior and applications.
