How are absorption lines produced
Web13 de jan. de 2024 · An absorption line is produced when a photon of just the right energy is absorbed by an atom, kicking an electron to a higher energy orbit. The photon had energy = the difference in energy of the energy orbits. Because the energy levels in an element's atoms are fixed, ...
