Emission spectra are produced by adulterate gases in which the atoms do not experience many collisions (because of the low density).

The emanation of yellow light occurs because the electrons of the atomic number 11 salt call forth been promoted to a higher electronic energy state only when have then fallen back down and emitted the energy as an electromagnetic wave, in the wavelength corresponding to yellow which is ? 600 nm. The more(prenominal) exquisite that the yellow band is the more abundant the sodium salt present.
