Radio waves are a form of electromagnetic radiation. All electromagnetic waves, including radio waves, visible light, X-rays, gamma rays, etc., travel at the same speed in a vacuum, which is the speed of light (approximately 299,792,458 meters per second). Their speed is slightly lower when passing through a medium like air, but it remains the same for all types of electromagnetic waves in that specific medium.
The velocity of radio waves is _____
