The reason for greater emission intensity of sodium lines at 589 and 589.6 nm for a solution containing KCl in comparison to the solution in which KCl is absent should be determined. Concept introduction: Spectral lines are lines which help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby. Sodium spectrum has bright doublet at 588.995 and 589.592 nm. This is said to be sodium D-lines. The intensity of the line at 589 nanometers is twice that of the intensity of the line at 589.6 nanometers.
