The excerpt below, about Rayleigh scattering, is taken from the following page: https://en.m.wikipedia.org/wiki/Rayleigh_scattering
Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency. The particle therefore becomes a small radiating dipole whose radiation we see as scattered light.
Is Wikipedia trying to say that the light wave is causing the electrons, themselves, to move at the same frequency as the incoming light (i.e. visible light)? If so, how can this be? From my understanding, an electron, when in its orbital, doesn't vibrate in a classical manner, and it's not even known where the electron is when in an orbital.
If Wikipedia is not referring to the electrons in their orbitals, then what might they be referencing?
