SUMMARY
Heinrich Hertz successfully measured ultra-high frequency (UHF) waves in the late 19th century using innovative experimental techniques that involved generating and detecting electromagnetic waves. Hertz's experiments demonstrated the existence of electromagnetic radiation, confirming Maxwell's theory. He utilized a spark gap transmitter and a simple receiver to create and measure standing waves, allowing him to calculate wavelengths and frequencies without modern instruments like oscilloscopes. His work laid the foundation for future developments in radio technology and wireless communication.
