Everything above absolute zero gives off radiation. We can only see a small fraction of that radiation. Some snakes see heat that we can see only with special equipment. Some insects see ultraviolet which we also need special equipment to see. We see the radiation in the colors that the sun gives off. At night we see very little. If something is heated hot enough, it gives off radiation close to the color that the sun gives off. You can see that when you look at a gas stove. You can see the hottest blue flame then a cooler yellow flame and then a cooler red flame. If you run electricity through some substances, you will heat them up until they give off heat or light. Thus, with certain materials you can heat a filament until it reaches the temperature where it gives off a white light. The filament is enclosed in glass to keep out oxygen. Otherwise the filament would burn up. So a filament gets real hot like a stove and then gives off light.
Florescent lights do not need to get nearly near as hot and use far less electricity. Soon there will be diode bulbs that use even less.
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
Some raw materials that can light a bulb include electricity (from a power source), a filament (usually made of tungsten), a glass bulb to contain the filament, and inert gases like argon or nitrogen to prevent the filament from burning. These materials work together to produce light when the filament heats up and emits photons.
The filament in an incandescent light bulb is typically made of tungsten. Tungsten is a metal with a high melting point that allows it to produce light and heat when an electric current passes through it.
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
the filament
A light bulb filament is a thin wire, typically made of tungsten, that is heated by an electrical current to produce light. As the filament heats up, it glows and produces light, making it a critical component in an incandescent light bulb.
If the filament in a light bulb breaks, the circuit is interrupted and the light bulb will no longer illuminate. This is because the broken filament is unable to produce light when electricity flows through it.
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
When electricity passes through the filament inside a light bulb, it heats up the filament to a very high temperature. This causes the filament to glow and emit light, a process known as incandescence.
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
A light bulb produces visible light when electricity flows through its filament, causing it to heat up and emit light. The color of the light produced depends on the type of filament and gases inside the bulb.
A light bulb radiates visible light when an electric current passes through its filament, causing it to glow and produce light.
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
When electricity flows through the filament in a light bulb, the filament becomes very hot and starts to emit light due to the process of incandescence. The electricity heats up the filament to a high temperature, causing it to glow and produce light.
