Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (shorter than a grain of rice); at 30 Hz the corresponding wavelength is 10,000 kilometers … See more Radio waves were first predicted by the theory of electromagnetism proposed in 1867 by Scottish mathematical physicist James Clerk Maxwell. His mathematical theory, now called Maxwell's equations, predicted that a … See more Radio waves are radiated by charged particles when they are accelerated. Natural sources of radio waves include radio noise produced by lightning and other natural processes in … See more Radio waves are more widely used for communication than other electromagnetic waves mainly because of their desirable propagation properties, stemming from their large wavelength. Radio waves have the ability to pass through the … See more Radio waves are non-ionizing radiation, which means they do not have enough energy to separate electrons from atoms or molecules, ionizing them, or break chemical bonds, … See more Radio waves in a vacuum travel at the speed of light $${\displaystyle c}$$ . When passing through a material medium, they are slowed … See more In radio communication systems, information is transported across space using radio waves. At the sending end, the information to be sent, in the form of a time-varying electrical signal, is applied to a radio transmitter. The information, called the See more Since radio frequency radiation has both an electric and a magnetic component, it is often convenient to express intensity of radiation field in terms of units specific to each component. … See more WebMar 6, 2024 · The speed of all electromagnetic waves in vacuum is equal to the speed of light. Thus all radio waves, i.e., longwave, shortwave, ultra-short wave radio waves, microwave waves; light waves, i.e., infrared to visible and ultra-violet light; and x-ray and gamma-ray waves all propagate at the same speed of approximately 300000 km/s.
