Heinrich Hertz

Heinrich Hertz was a German physicist who made significant contributions to electromagnetism in the late 19th century. He was the first to experimentally demonstrate the existence of electromagnetic waves, confirming James Clerk Maxwell’s theories. Hertz's experiments involved generating and detecting radio waves, establishing the foundation for wireless communication. His work showed that these waves travel at the speed of light and can reflect, refract, and interfere like sound waves or light. This groundbreaking research paved the way for various technologies, including radio, television, and modern wireless communication systems.
