Waves of water and sound.

[reverse]

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?

[ydoaPs]

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.

What medium do Radio waves travel in?

 

space.

[akcapr]

magnetic waves travel throo earths magnetic field right

[reverse]

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?

[Primarygun]

Electromagnetic waves can travel through vacuum while the other cannot.

They can also travel at a lower speed in other media.

[Zeth]

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.

[Anjruu]

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.

[ydoaPs]

what do you mean? it is easy to understand. just take it at face value: particles aren't just particles, but also waves.

[ecoli]

space.

 

Technically, space isn't a medium, only a lack of one. I'm I right?

[ydoaPs]

not really. it is the medium for gravity waves.

[J.C.MacSwell]

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?

 

For the record...No.

 

Water waves are gravitational/mass displacement waves.

 

Compression/expansion waves in water are sonic (sound) waves.

[ydoaPs]

i thought water waves were transverse, but i couldn't remember.

So is light like this

or like this

[Ophiolite]

Yes

[reverse]

lol.

 

the two situations seem mutually exclusive.

 

how do you ease the apparent paradox?

 

 

 

 

like this?

Well, that's almost as scary as the paradox itself.....
