A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be compared to the previously collected ones of atoms and molecules, and are thus used to id… Web21 sep. 2024 · This time, if the electrons move up 4 energy levels with this one specific wavelength they have absorbed, then you can't see the 4 other wavelengths that were emitted?
