Radio frequencies travel at what speed?

Radio frequencies travel at the speed of light. This is a fundamental principle of physics that applies to electromagnetic waves, which includes radio waves. The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second). This high speed ensures that radio communications, such as those used in broadcasting or wireless networking, can transmit signals over large distances almost instantaneously.

Understanding that radio waves are a type of electromagnetic radiation helps clarify why they travel at this speed; they share the same properties as light and other forms of electromagnetic radiation. This characteristic is crucial for effective communication technologies, allowing signals to be sent and received quickly across various distances and conditions.
