To produce the light. When it gets heated, it glows.
It heats up when a current is passed through it and, as it gets hotter, it glows and radiates energy in the visible spectrum.
It is known as filament. filament

Three parts of an electric bulb might include the filament, the actual bulb, and the base.
Thomas A. Edison
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
The scientific name for an electric bulb is incandescent light bulb, named after the process of incandescence which produces light through heating a filament.
This was called a filament and was found in older electric light bulbs.
Because the filament will burn, and the filament is the part that produces the light.
