Does electricity travel faster through air or water?

Answer 1

Since ice is a solid, the molecules that make it up are a lot more closely packed then in water. Also, water is one of the few substances that grow in volume when frozen this may give the electrons in an electrical current more room to move through the solid object.

Answer 2

Technically the speed at which light, or any radiation for that matter, goes through

a medium is the same, it must first bounce off all the particles in the medium

before exiting.

That said; ice is less dense than water and therefore has a refractive index lower

than it, by ~.024. This means that it's easier for the light to travel in a straighter,

and therefore shorter line in a less dense substance, than a more dense substance.

The more dense a substance is, the more atoms there are in a given space means

that in that space, the light has to bounce off of each individual particle as opposed

to a less dense substance, which occupies less atoms in a given space, and therefore

has less atoms for the light to bounce off of.

Sounds reasonable ... except that ice is lessdense than water ? ?

[Better?]

[Yep!]
