The interaction between electron in orbit and a photon (a proposed dipole) is electrostatic. The photon is in a helical path, on approach towards the atom, the orbital radius of the electron is squeezed to a lower value. The energy is stored as developed in "Like Wave, Like Particle, Not Attracted to Electrons", because of orbital speed at light speed cannot be increased further,
Consider the post "Pag.Pag...Pag....Pag Dnab Ygrene", a packet of energy is emitted when the photon transit to a higher orbit pass a kink point in the \(r_e\) vs \(T\) profile, that means the light reflected off the surface of the metal is brighter than the incident light. This is the common glare we experience from shiny surface. In fact this is the reason way some surfaces are so shinny; there are more photons on reflection than incident.
Next up, how much energy the photoelectric photon lose on passing?
