None, the inside is a vacuum.
The two gases commonly used in incandescent light bulbs are argon and nitrogen. The gases help prevent the filament inside the bulb from oxidizing at high temperatures, prolonging the bulb's lifespan.

The filament in an incandescent light bulb is typically made of tungsten.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
The average lifespan of an incandescent light bulb is around 1,000 to 2,000 hours.
The gas inside a standard incandescent light bulb is typically an inert gas, such as argon or a mixture of argon and nitrogen. These gases help to prevent the filament from oxidizing and burning out quickly when heated. In some compact fluorescent and LED bulbs, other gases or materials are used to produce light, but traditional incandescent bulbs mainly utilize these inert gases for efficiency and longevity.
Yes, light in an incandescent bulb is a form of electromagnetic radiation, not matter. The light is produced by the heating of a tungsten filament in the bulb, causing it to emit visible light.
A light bulb that uses a filament is also known as an incandescent light bulb.
Incandescent
He named his invention the Incandescent Lamp, But it's commonly referred to today as the Incandescent Light Bulb.
An incandescent bulb emits a continuous spectrum of light, which includes all colors of the visible spectrum.
The incandescent electric light bulb was invented by Thomas A. Edison.
