Actually, radio waves travel very quickly through space.
Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light.
The speed of light is a little less than 300,000 km per second.
At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.
How fast is a radio signal?
Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km. Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum.
How long can radio waves travel?
Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers).
Bands of radio waves.
|Band||Frequency range||Wavelength range|
|Very Low Frequency (VLF)||3 to 30 kHz||10 to 100 km|
|Low Frequency (LF)||30 to 300 kHz||1 m to 10 km|
