In flame photometry, which color corresponds to sodium emission?

Explanation:
In flame photometry, light comes from atoms in the flame that are excited and then relax, emitting photons at specific wavelengths. Sodium has its strongest emission at about 589 nanometers, which lies in the yellow region of the spectrum. When sodium atoms emit, that yellow light is produced, so the observed color for sodium emission is yellow. The other colors would correspond to emissions from other elements, not sodium, which is why yellow is the correct choice.
