The unit of frequency, known as the hertz (Hz), is named in honor of Heinrich Hertz, a German physicist recognized for his significant contributions to the field of electromagnetism. Hertz was the first to conclusively prove the existence of electromagnetic waves, which laid the foundation for the development of modern wireless communication technologies. His groundbreaking experiments demonstrated how radio waves could be generated and detected, which fundamentally changed the understanding of electromagnetic radiation. As a result, the frequency of a wave, measured in cycles per second, was named after him to commemorate his influential work in physics, particularly in the study of wave phenomena.
