Is the generation of light by an electric lamp a chemical or physical change?
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
