Aug 10, 2016 · WHAT ARE RADIO WAVES? Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet. Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on […]

The discovery that electromagnetic radiation in the microwave and radio regions of the spectrum displays the same basic behavior as visible light—reflection, refraction, diffraction, interference, polarization—was made in Karlsruhe in 1888 by Heinrich Rudolf Hertz.
HERTZ, HEINRICH. HERTZ, HEINRICH (1857–1894), German scientist.. Heinrich Hertz's name has been given to a unit of frequency, an honor he received because he was the first person to produce electromagnetic waves (radio waves) artificially and to demonstrate that their behavior is similar to that of light (1886–1888).
German physicist who experimentally proved the existence of electromagnetic waves in 1888. His apparatus consisted of a wire connected to an induction coil to produce the waves and a small loop of wire with a spark gap to detect them.
The Beginnings of Radar INTRODUCTION: This information sheet is intended to provide the technician with some of the background history and development of radar, especially as it relates to the use of the technology in the field of meteorology
German physicist Heinrich Hertz discovered radio waves, a milestone widely seen as confirmation of James Clerk Maxwell’s electromagnetic theory and which paved the way for numerous advances in communication technology.
