Homework Help: Science

Posted by Lizzie on Monday, January 25, 2010 at 6:09pm.

I needed help with this question. Iím not sure I got it quite right.

Is it correct to say that in every case, without exception, any radio wave travels faster than any sound wave?

ANSWER: Yes, it is correct to say because radio waves are electromagnetic waves, and travel at the speed of light. They do not need a media of any type to move through. Sound waves travel at various speeds depending on the media they are transmitted in, but there is nothing they can go through that can make them travel at the speed of light.
