reverse Posted May 28, 2005 Share Posted May 28, 2005 Water waves are a compression and expansion of water. So… water waves travel in water. And… Sound waves travel in air. What medium do Radio waves travel in? Link to comment Share on other sites More sharing options...
ydoaPs Posted May 28, 2005 Share Posted May 28, 2005 they don't need one. radio(light) is an EM(electromagnetic) wave. it is an alternating electric and magnetic field acting perpendicular to the direction of the wave. Link to comment Share on other sites More sharing options...

akcapr Posted May 28, 2005 Share Posted May 28, 2005 magnetic waves travel throo earths magnetic field right Link to comment Share on other sites More sharing options...
reverse Posted May 28, 2005 Author Share Posted May 28, 2005 we get signals from space probes right? So are you saying you can compress and rarefy space … I thought space was almost a prefect vacuum? Link to comment Share on other sites More sharing options...
Primarygun Posted May 28, 2005 Share Posted May 28, 2005 Electromagnetic waves can travel through vacuum while the other cannot. They can also travel at a lower speed in other media. Link to comment Share on other sites More sharing options...
Zeth Posted May 28, 2005 Share Posted May 28, 2005 I believe that in classical mechanics the Aether was introduced to explain how they could move through space. It was not until relativity that that was rejected. Link to comment Share on other sites More sharing options...
Anjruu Posted May 28, 2005 Share Posted May 28, 2005 Radio waves are also photons, and particles can travel through vacuum. I believe that this property is one of the particle-states of light. How a wave can be a particle and vice versa is something I think nobody understands, much less a high school physics student. Link to comment Share on other sites More sharing options...
ydoaPs Posted May 28, 2005 Share Posted May 28, 2005 what do you mean? it is easy to understand. just take it at face value: particles aren't just particles, but also waves. Link to comment Share on other sites More sharing options...
ecoli Posted May 28, 2005 Share Posted May 28, 2005 space. Technically, space isn't a medium, only a lack of one. I'm I right? Link to comment Share on other sites More sharing options...
ydoaPs Posted May 28, 2005 Share Posted May 28, 2005 not really. it is the medium for gravity waves. Link to comment Share on other sites More sharing options...

What medium do Radio waves travel in? For the record...No. Water waves are gravitational/mass displacement waves. Compression/expansion waves in water are sonic (sound) waves.

reverse Posted May 28, 2005 Author Share Posted May 28, 2005 lol. the two situations seem mutually exclusive. how do you ease the apparent paradox? like this? http://www.studyworksonline.com/worksheets/Composition/Images/C1LS_Roller_Coaster.jpg Link to comment Share on other sites More sharing options...
Ophiolite Posted May 28, 2005 Share Posted May 28, 2005 Well, that's almost as scary as the paradox itself..... Link to comment Share on other sites More sharing options...
