What is speed of radio transmission?

Answer 1

186,000 miles per second

Answer 2

Radio waves will travel at the speed of light, just as all other electromagnetic (EM) waves do. This speed is 299,782,458 metres per second in a vacuum. The speed of EM radiation varies as the medium through which it is moving, and it will not move as quickly in any media as it does in a vacuum.

Answer 3

Radio waves can travel 300,000km per second. If someone was dialing from the moon to the earth, a signal would arrive in about 1.3seconds. The distance from the moon to the earth is 390,000km.

Answer 4

They travel at the speed of light becouse they are a type of light! (electromagnetic radiation to be exact)

But at different wavelength. Radio wavelength is between 1mm - 100km, visible light is between 380nm - 740nm

Answer 5

v = c/n (c is the speed of light and n is the refractive index of the media where a radio siganl is traveling).

Answer 6

Like all other electromagnetic waves, they travel at the speed of light.

Answer 7

Radio signals travel at the speed of light

Answer 8

186,000 miles per second
