Is fire luminescent

Answer 1

Yes, fire can be considered luminescent because it emits light as a result of a chemical reaction during combustion. The light produced comes from the excitation of gas molecules and particles in the flame, which release energy in the form of visible light when they return to their ground state. However, fire is distinct from other forms of luminescence, such as fluorescence or phosphorescence, as it is a result of a high-temperature reaction rather than a non-thermal process.
