Question

why fire produce light

Answer 1

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.

Answer 2

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.
