Radio frequency (RF) itself doesn't have a "speed". It's a *range of frequencies* used for radio waves.

What travels at a specific speed is the electromagnetic radiation itself, including radio waves.

The speed of all electromagnetic radiation in a vacuum is the speed of light:

* Approximately 299,792,458 meters per second (m/s)

* Or about 186,282 miles per second (mi/s)

This speed is constant, regardless of the frequency of the radio waves. So whether it's AM radio, FM radio, or the signals from your cell phone, they all travel at the speed of light.

Important Note: The speed of radio waves can be slightly slower when they travel through a medium other than a vacuum, like air or water.
