At what speed does radio frequency travel?

Radio frequency travels at the speed of light, which is approximately 299,792 kilometers per second (or about 186,282 miles per second) in a vacuum. This speed is not only fundamental to the transmission of electromagnetic waves, such as radio waves, but it also plays a crucial role in the field of communications and technology. Understanding that radio frequencies are a part of the electromagnetic spectrum—which includes visible light, microwaves, and X-rays—clarifies why they propagate at this incredible speed.

The speed of sound, on the other hand, is considerably slower, traveling at roughly 343 meters per second in air at room temperature. This highlights the vast difference in speed between mechanical waves (like sound) and electromagnetic waves (like radio frequencies). While speed of Wi-Fi and speed of electricity may suggest other forms of signal propagation, they do not equate to the inherent speed of electromagnetic radiation, such as radio frequencies.
