What is the 3D model of the radio signal?

Question

Physics

What a 3D model of a radio signal looks like and how it propagates, in some scientific and scientific articles they write about the frequency and wavelength, but this does not give an idea about the wave itself. And what does all this have to do with color?
If it is not difficult to explain without analogues, otherwise analogues are always inaccurate.

Answer 1

If it is not difficult to explain without analogues, otherwise analogues are always inaccurate.

Easily.
The 3D model of the radio signal is described by Maxwell's equations, and the latter are described in many places .
In relation to a radio signal, they often also talk about a plane wave - the simplest particular case, described by frequency or wavelength, and amplitude. If this does not give an idea about the wave itself, then something is wrong with your imagination: it gives it to everyone else.
How is wavelength related to color - you're not dumb enough to not be able to ask Google, are you?

Answer 2

Read here (very clear and in Russian).
Here is Maxwell's system of equations in all its glory:

∇·E = ρ/εo                      Закон Гаусса для E
∇×E = – ∂B/∂t                   Закон Фарадея
∇·B = 0                         Закон Гаусса для В
∇×B = j/εoc2 + (1/c2)·∂E/∂t     Теорема о циркуляции В

It describes absolutely all electromagnetic phenomena. And now you understand it (at least, I hope so).

Answer 3

Depends on the shape of the antenna
