How does flames work using radiation?

Flames produce light and heat through the process of combustion, which releases energy in the form of electromagnetic radiation. This radiation includes visible light, infrared, and ultraviolet light, generated by the excitation of atoms and molecules during the combustion process. As the hot gases and soot particles in the flame emit energy, they can radiate heat to surrounding objects, contributing to the warming effect of the flame. Ultimately, the visible glow of the flame is a result of the thermal radiation emitted by these excited particles as they return to lower energy states.
