Radio wave - Wikipedia
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 …Wikipedia · CC-BY-SA உரிமத்தின் கீழுள்ள உரை23.1: The Electromagnetic Spectrum - Physics LibreTexts

Electromagnetic spectrum - Wikipedia
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each o…
