Radio waves make up the part of the electromagnetic spectrum with the longest wavelengths. Radio waves are used in radio and television broadcasts, satellite transmissions and cell phone signals. Astronomical objects give off radio waves which can be detected by radio telescopes.


Radio waves are a type of electromagnetic radiation with a very long wavelength that are emitted by sources that include astronomical objects and television and radio transmitters. Radio waves, the longest wavelengths in the electromagnetic spectrum, typically carry radio, television and cellphone s


Radio waves work as a form of electromagnetic radiation. They are a mixture of magnetism and electricity that moves at the speed of light with a defined length and frequency.


KIIS-Los Angeles, Z100-New York, BBC Radio 1, Star 94-Atlanta and XM Top 20 on 20 are all popular radio stations. Although these stations broadcast to a limited regional market on FM/AM wavelengths, most of them are also accessible online via individual official station websites.

Radio waves travel at a velocity that is equal to the speed of light traveling in a vacuum, which is 186,282 miles per second. Top speed is only possible in empty space; passing through transparent liquids and solids like crystals cause waves to bend, which slows down their speed.


Some properties of radio waves, which are a type of electromagnetic radiation, are that they have the longest wavelengths and the shortest frequencies on the electromagnetic spectrum, The wavelengths of radio waves are greater than 4 inches. Radio waves also can be subdivided into different groups t


The speed of radio waves is approximately 186,000 miles per second, which is also the speed of light. The reason that radio waves travel at the speed of light is that they are a type of electromagnetic radiation. Other forms of electromagnetic radiation are X-rays and light.
