WebMay 22, 2024 · 1. If the initial source of energy for spontaneous emission is supplied optically, the process is called photoluminescence. Glow in the dark materials emit light … WebEmission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. When light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands.
WebIn physics, emission is the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through the emission of a photon, resulting … WebLine emission and absorption spectra Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When matter is very hot it emits light.
