A Question To The Experts Here
Does the speed of the wave is the same as the speed of it through space or the atmosphere for that matter
i say no
i say the speed is different when a wave passes through different medium
i give no scientific proof of that
who here has that proof
please comment, i am all ears

One of Maxwell's equation is Ampere's Law.
Some solutions of it derive E and M waves.
In the equation, the permeability of free space and
the permittivity of free space determine the speed of the wave.
The dielectric and magnetic properties of materials
modify these free space constants, thus the velocity of the wave.
A typical college physics or EM text explain these concepts.
Start with Google.

There are no beaches in space.
What sort of wave are we talking about?
