Na spectral lines occur due to the quantum nature of sodium atoms. The electrons in sodium atoms occupy specific energy levels, and when energy is absorbed or emitted, the electrons transition between these levels. The energy difference between the levels corresponds to the wavelength of light emitted or absorbed, resulting in a discrete set of spectral lines. Studying these lines provides insights into atomic structure, quantum mechanics, and astrophysical phenomena such as stellar atmospheres and exoplanet atmospheres.
