B. radio waves travel at the speed of light. This is why we are able to listen to live radio and watch live tv without a time lag. By the way the speed of radio waves is not the same as the speed of sound. I assure you radio waves travel at the speed of light

If you have to choose - so the second one. Because the speed of sound is about 300 m/s and the speed of light is 300000km/s. The speed of radio waves is the speed of electromagnetism and this is the same like the speed of light!

The answer is b. same as the speed of radio waves
as all electromagnetic radiation -- from radio waves to x-rays -- travel at the speed of light. In empty space this speed is approximately 300,000 kilometers per second!

Light and radio waves are both electromagnetic waves. Therefore they would most likely travel at the same speed.

The speed of light is 186,355 miles per second.
Since I know that the speed of sound is slower, I can only guess that radio waves are the same as speed of light.

It's definitely not the speed of sound. Think about a thunderstorm, you see the lightening and then you hear the thunder. I don't know about radio waves but I assume they're faster than the speed of sound. Good luck!

B radio waves are part of the electro magnetic spectrum and so is light. So they all have the same speed.
