Yeah, I'm slightly confused by this topic as well. From my understanding, I think that it refers to the specific emissions of light that are emitted when a particular atom's valence electron(s) become excited and move from one energy state to another.

Am I wrong, and what more is there to know about the fundamentals behind this concept ?

Atomic Absorption Spectroscopy is a technique the light than ions will absorb when electrons get excited in heat (aka a flame). It is used to determine the atoms and concentration of a sample. Atoms of the light are excited over the flame and the energy difference is tested, because energy difference when changing energy levels is different for different atoms, which allows us to know our sample. Furthermore, light is absorbed only at an exact wavelength for each different atom. This technique allows us to figure out which atom of the sample it is and the concentration of it.
