It is vaccum.
Incandescent light bulbs and halogen light bulbs are examples of light bulbs that produce heat.
Light bulbs are filled with argon instead of air because argon is an inert gas that helps prevent the filament from oxidizing and burning out quickly. Air contains oxygen, which can cause the filament to degrade faster due to oxidation. Argon creates a more stable environment inside the bulb, prolonging the life of the filament.
A ray of light in the air is a thin beam of light traveling through the atmosphere. The ray can be produced by natural sources like the sun or artificial sources like light bulbs. It can be seen as a visible stream of photons passing through the air.
Light bulbs emit electromagnetic radiation, specifically visible light, to produce light.
White light bulbs typically have a higher color temperature and appear brighter than yellow light bulbs. White light bulbs emit a cooler, bluish light, while yellow light bulbs emit a warmer, more yellowish light.
Usualy air getting into them.
Argon does not react. :)
Light is not used in light bulbs; light is created in light bulbs. From Edison to the invention of solid state devices, light bulbs were mostly incandescent. They made light by running electricity through a tungsten filament inside a glass bulb with the air removed. The filament got very very hot and emitted light waves (photons). The lack of air (oxygen) preserved the filament from burning up. The efficiency was atrocious, but they made light.
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.

why light bulbs are fragile
In some light bulbs.
Light bulbs emit light.
It would no longer work. Light bulbs are usually under vacuum and if air gets in the filament blows.
