Types of light-matter interaction I'm going to study the photoionization, that is the emission of an atom's electron because of it's interaction with EM radiation.
To contextualize it, I would like to know what other effects can the light-matter interaction lead.
 A: without being exhaustive, here are a few examples:

*

*Reflexion on a metallic surface: interaction between the free electrons of the metallic body and the incident light wave. Basis of the part of optics dealing with mirrors.

*Bragg diffraction: interaction of a light wave with the electrons of atoms regularly spaced in a cristalline lattice. Used to study cristalline structures.

*Other cristalline lattice / light interactions: LEDs (diodes), LASER diodes, .

*Refraction:  Interaction of light with an amorphous transparent body (glass, water, air) where light rays change course due a change in index (light velocity in a given body). This is the basis of the part of optics dealing with lenses.

*Excitation of atomic or molecular energy states (transitions between levels of energy): Basis for the Laser. Also the mechanism behind fluorescence phenomena, phosphorescence.

*Black Body radiation : Light (distribution) emitted by a body at a given temperature: example: A light bulb or a star or an oven.
