Hertz Experiment
The Hertz Experiment, conducted by Heinrich Hertz in the late 19th century, demonstrated the existence of electromagnetic waves. Hertz used a wire loop to create sparks, which emitted waves that could be detected remotely by another loop. He showed that these waves could travel through the air, just like light, leading to the discovery of radio waves. Although Hertz didn’t understand their practical applications at the time, his work laid the foundation for modern wireless communication, including radio, television, and cellular technologies, fundamentally changing how we connect and share information.

The Hertz experiment, conducted by Heinrich Hertz in the late 19th century, demonstrated the existence of electromagnetic waves, which are a type of radiation that includes radio waves. Using a high-voltage spark gap, Hertz produced these waves and showed that they could be transmitted through the air and reflected from surfaces, similar to light. His work validated James Clerk Maxwell's theories about electromagnetism and laid the groundwork for modern wireless communication technologies, such as radio and television. Hertz's findings revealed that electromagnetic waves travel at the speed of light and can carry information over distances without physical connections.
