Splet25. jul. 2024 · 1. For most flames, the color is simply a measure of the temperature of the glowing gas. The spectrum of the flame is fairly close to a black body, with a bluer peak in the spectrum indicating a higher temperature. So what you are seeing is that the flame is hotter lower down. This can be seen in gas jet flames or in match flames. SpletOnce those electrons relax back to their ground states, photons will be emitted, and the atom or molecule will give off visible light of specific frequencies.
