No, it is actually a microwave wave.

Light is an electromagnetic wave; and those are transverse. Sound is usually a longitudinal wave.
Sound isn't. The others are.
The shortest radio wave (300 GHz) is something like 1,300 times as long as the longest visible light wave (750 nm).
Every radio wave has a different length. It depends on the frequency and is inversely proportional to the speed of light. K1ATV, Mesa AZ
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
gamma ray
Sound.
it travels in an em ( electromagnetic wave) ranging from gamma rays to radio waves
