- TL;DR Summary
- Interaction of light with atoms. Two ways of describing.
One description of the interaction light with atoms states "Light waves incident on a material induce small oscillations in the atoms, causing each to radiate a small secondary wave in all directions". And another that "A photon with the right energy causes an electron to jump up to the next higher energy level, eventually dropping back to the lower state with the emission of a photon". How do these two relate?
