I have read so much, please put me straight on "photon interaction"
1. My photon hits matter.
2. It interacts with the atoms of that matter.
3. The electron (say) energy level transition (High->Low) spawns photon(s) of lower energy levels?
4. My photon is now other photon(s) but energy conserved ?
5. In terms of refraction, is this what is the happening??
