WebAn emission spectrum occurs when the atoms and molecules in a hot gas emit light at certain wavelengths, causing bright lines to appear in a spectrum. As with absorption spectra, the pattern of these lines is unique for each element. We can see emission spectra from comets, nebula and certain types of stars.

WebThis process is called emission because a photon of light is emitted by the atom, again at a very specific wavelength. Of course, the atom could have absorbed another photon with just the right energy to jump up another energy level, or even two or three or more. ray wilson rhianneWebIf a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion. ray wilt motorcycleWebWhat is Emission of Light?
