Radio waves, microwaves, infra-red, visible light, ultra violet, X-rays, and gamma rays are all part of the ‘electromagnetic spectrum. They are all electromagnetic radiation and they all travel at the speed of light. The only difference between them is their frequencies (or wavelengths).

Radio waves are a type of electromagnetic radiation with wavelengths longer than infrared light. They are made by lightning or astronomical objects, but can be artificially created by radio, broadcasting, and radar.

Radio waves travel at the speed of light like all other electromagnetic radiation. There are different frequencies of radio waves which can propagate the Earth’s atmosphere differently. Long radio waves can cover the Earth consistently, while short radio waves bounce off the ionosphere.
