Web25 de nov. de 2024 · Hertz proved the existence of radio waves in the late 1880s. He used two rods to serve as a receiver and a spark gap as the receiving antennae. Where the waves were picked up, a spark would jump. Hertz showed in his experiments that these signals possessed all of the properties of electromagnetic waves. WebHeinrich Hertz. To produce a radio wave, Hertz used a high voltage induction coil that produced an AC voltage signal with a frequency of about 300 million hertz. The high voltage made it possible charges to cross a narrow gap between between two brass spheres at the ends of a semi-circular conducting loop, creating sparks.

In 1864 Scottish mathematical physicist James Clerk Maxwell proposed a comprehensive theory of electromagnetism, now called Maxwell's equations. Maxwell's theory predicted that coupled electric and magnetic fields could travel through space as an "electromagnetic wave". Maxwell proposed that light consisted of electromagnetic waves of short wavelength, but no one had bee… Web25 de set. de 2024 · Among the most influential and well-known experiments of the 19th century was the generation and detection of electromagnetic radiation by Heinrich Hertz in 1887–1888, work that bears favorable comparison for experimental ingenuity and influence with that by Michael Faraday in the 1830s and 1840s.
