How fast do am radio waves travel
WebRadio wave speed is approximately 300,000,000 meters per second. It travels in a vacuum at the speed of light, which is the highest velocity that exists. The discovery of … 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 …
