How were radio waves discovered
In 1894, the young Italian inventor Guglielmo Marconi began working on the idea of building long-distance a wireless transmission systems based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. Marconi read through the literature and used the ideas of others who were experimenting with radio waves but did a great deal to dev… WebThe creation of an electromagnetic wave begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
