What are radio waves? NASA
Web20 apr. 2024 · Radio waves move at roughly 186,000 miles per second, which is the speed of light. But then this question also arises, Do all radio waves travel at the same speed? All electromagnetic waves move at the same speed, whether radio, visible, or gamma. They all go in a vacuum at the’speed of light,’ which is 3 10 8 m s-1. Radio waves in a vacuum travel at the speed of light . When passing through a material medium, they are slowed depending on the medium's permeability and permittivity. Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light. The wavelength is the distance from one peak (crest) of the wave's electric field to the next, and is inversely proportional to the frequency of the wave. The relation of frequency and wavelength in … great learning icon
