Considering this, why do fire have light?
In fires, chemical reactions release heat, releasing gases and raising materials to high temperatures, where the materials and the gases incandescence. Different temperatures are produced and result in different colors. Since fire is made up of an intense reaction, electrons jump between shells, which emit light.
How does fire gives off light?
When the matter gets hot enough, that emission will include visible light. This is called incandescence. When you look at a fire you are looking at volatile gas molecules that arise from the burning and vaporization of the material being burned. Those atoms are incandescent.
Is a fire a source of light?
Natural sources of light include the sun, stars, fire, and electricity in storms. Artificial light is created by humans. Flashlights, table lamps, neon signs, and televisions are some sources of artificial light.
