WebA frequently used method involves that a tunable narrow-linewidth laser (frequently a single-frequency laser) is tuned through some wavelength range, and the light absorption in some sample is measured as a function of that wavelength. The absorption is often obtained by measuring (a) the optical power of a laser beam which is transmitted through the … WebPhoton absorption by an atomic electron occurs in the photoelectric effect process, in which the photon loses its entire energy to an atomic electron which is in turn liberated from the atom. This process requires the incident photon to have an energy greater than the binding energy of an orbital electron.
