WebNo two elements emit the same set of spectral lines, therefore, elements can be identified by their line spectrum; There are two types of line spectra: emission spectra and absorption spectra; Emission Spectra. When an electron transitions from a higher energy level to a lower energy level, this results in the emission of a photon WebAn energy level is regarded as degenerate if there is more than one measurable quantum mechanical state associated with it. Explanation ... The first evidence of quantization in atoms was the observation of spectral lines in light from the sun in the early 1800s by Joseph von Fraunhofer and William Hyde Wollaston.
