And I'm still awaiting a response to my post. You know, one where you actually show mathematically that your system of three electrons that you were using to model this interaction can absorb a photon and still conserve both momentum and energy, rather than just making vague references to radio antennae. |
Vague, vague?
It isn't vague at all.
momentum is only conserved if there are no external forces acting. In "physics according to Sylas volume 1" he expects momentum to be conserved, but we don't.
The momentum of the electron in a direction perpendicular to that in which the photon was originally travelling is not conserved because there is an external force acting on it - due to the oscillating electric fields of the photon. This is why it
gains energy and momentum in this direction.
If one wants momentum to be conserved then one must look at the universe as a whole - including when the photon was transmitted.
A wibbly wobbly when it was created is cancelled by a wibbly wobbly when it was absorbed.
