What happens to the energy of an absorbed photon?

WebIntroduction. Tunable vacuum ultraviolet (VUV) radiation plays an important and growing role in current molecular physics research. Narrowband VUV, for example, was key in metrological measurements of the ionisation potential and dissociation of energy of H 2, shown by Ubachs and co-workers [Citation 1] to provide sensitive tests to the stability of … WebThe electrons accelerate as they return to the parent ion, releasing higher energy photons at diminished intensities, which may be in the EUV range. If the released photons constitute ionizing radiation, they will also ionize the atoms of the harmonic -generating medium, depleting the sources of higher-harmonic generation. dynamic world remote sensingWebMar 27, 2024 · The energy of a photon depends solely on its wavelength or frequency.
