Six different methods of producing light
Bioluminescence is making light using chemical reactions in living things.
Chemiluminescence occurs when light is released during a chemical reaction.
Fluorescence is like electric discharge, but the inside of the glass tube is coated with phosphor and the gas particals emit (invisible) ultraviolet light, which the phosphor converts to visible light.
solar fusion is when a proton reacts with a beta particale to form an alpha particale and energy.
Incandescence is burning fuel, such as wood, produces light.
Phosphorescence makes light by absorbing and slowly releasing ultraviolet light.
