Can all light-matter interactions be reduced to the photoelectric effect, the Compton scattering, and pair production?

My book says that all interaction of light and matter can be reduced to the photoelectric effect, the Compton scattering and pair production. How true is this?

What about reflection and absorption and emission and blackbody radiation and all that stuff?

• Write down the Feynman diagram for each and behold. – Cosmas Zachos Feb 15 '18 at 13:36
• I guess this is technically true but a bit weird. It's true if you're considering any interaction of the form $\gamma + \text{charge} \to \gamma + \text{charge}$ to be "Compton scattering", though we usually reserve that phrase for when $\gamma$ is an X-ray and the charge is an electron. – knzhou Feb 15 '18 at 14:25
• Then reflection is Compton scattering, absorption is photoelectric, emission is the same as absorption but backwards, blackbody radiation is the same as emission. – knzhou Feb 15 '18 at 14:25
• You might want to comment on the domain the book covers. The word "all" may very well be intended to mean "everything in our domain of interest" rather than being unqualified and all-embracing. Knowing how to read that kind of intent is one of the soft skills that our developed by doing a systematic study of the field. – dmckee Feb 15 '18 at 17:02
• Maybe you could mention the source of this assertion. The comment by @dmckee makes sense. – freecharly Feb 15 '18 at 18:43
