RF Energy travels at the speed of what?

Explanation:
RF energy is electromagnetic energy, so it travels as electromagnetic waves. In a vacuum, all electromagnetic waves move at the speed of light, about 3 x 10^8 meters per second. In air or typical media, the speed stays essentially the same for practical radar purposes because the refractive index is only slightly above 1, so v ≈ c / n with n ≈ 1.0003, i.e., still nearly the speed of light. This is why RF energy travels at the speed of light rather than the much slower speed of sound or some other value.
