In a vacuum, all electromagnetic waves travel at approximately 3 x 108 m/s - the fastest speed possible. When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum. The value for light travelling through an optical fibre, for example, is taken as 2 x 108 m/s.
Radio waves travel at the speed of light, 186,000 miles per second. How long would it take for a radio message to travel from Earth to the moo... Radio waves, visible light, infrared, ultraviolet, X-rays, and gamma rays are all the same thing - photons. They just carry different energy per photon, and therefore oscillate at different frequencies. The higher the energy, the higher the frequency.
