- Fire emits light through two primary mechanisms123:
- Incandescence: Small particles in the flame glow incandescently because they are hot, similar to how an incandescent light bulb works.
- Electronic transitions: Excited atoms in the flame produce light as a byproduct of the combustion process. The color of the flame can be influenced by the elements present in the burning material.

Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases m…
