Web"One sees at the specific position [of the lithium line] a bright line on a dark background; for a greater intensity of incident sunlight, however, there appears at the same place a dark line, having exactly the same character as Fraunhofer's lines." Kirchhoff also used incandescent lime, which was known to give off a continuous spectrum. Weba spectral line, at a wavelength that depends on the separation between the steps. With many excited atoms, many electrons are moving between steps having different separations and a variety of wavelengths is emitted. Quantum mechanics explains that for each type of atom, the relative positions of the steps are fixed, so distinct wavelengths
