It depends on what you would classify as the actual invention of the light bulb. Humphry Davy first invented an electric light in 1800, which consisted mainly of a battery and carbon. In 1878, Sir Joseph Wilson Swan created new, longer-lasting electric lamps, which he showcased in England. Thomas Edison, after working with thousands of different prototypes, discovered the light bulb that could glow for over 1500 hours, laying the foundation for light bulbs today.
The filament in a light bulb is typically made of tungsten.
The filament in an incandescent light bulb is typically made of tungsten.
Humphry Davy's invention of the first electric light bulb in 1800 was made possible by Alessandro Volta's invention of the electric battery in 1800. The electric battery provided a stable and continuous source of electric current needed to power the light bulb.
Yes, the inside of a light bulb is vaccum sealed to increase the lifespan and brightness of the bulb. If there was air in there, the filiment would burn up and not last very long. This was an important discovery made by Thomas Edison when he invented the light bulb.
A light bulb is made by creating a glass bulb, evacuating it of air, adding a tungsten filament, sealing the bulb, and then connecting it to a power source to produce light when heated. The process is carefully controlled to ensure the right conditions for generating light efficiently and safely.

No. Laser light is coherent. Light bulb light is not.
in 1856 Edison made the first light bulb :]
A light bulb is made from Ukraine by 2000 workers that die per bulb

There were three people that made the 1st light bulb. The three people that made the light bulb are Thomas Edison, Joseph Swan and Haram Maxim.

because the bulb is blown !

i think because it made light and it was a bulb
