when a current pass through a conductor it will heat it and raise its temperature, electrons will starts vibrating the conductor's atoms. Bound electrons in the vibrating atoms may be boosted temporarily to a higher energy level. When they fall back to their normal levels, the electrons release the extra energy in the form of photons. when a conductor is overheated it will melt down, tungsten is used in light bulbs since its meltdown temperature is very elevated. more than 90% of the released energy falls in the infrared range which is invisible to human eyes and only 10% of the emitted radiation is visible.

Tungsten emits light when heated because of its high melting point and conductivity. As it heats up, the tungsten atoms gain energy and begin to vibrate, causing the release of photons in the form of visible light. This light emission is what is commonly observed in incandescent light bulbs and other tungsten-based light sources.

Do galaxies emit light?
Yes galaxies emit light
What type of gas is in a tungsten-halogen light bulb?
Halogen gas is in a Tungsten-Halogen Light Bulb.
Does earth emit or reflect light?
The earth does not emit light, but it does reflect light from the sun.
What does amps do in a light bulb?
Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
Do you use hair to make a light bulb?
No, hair is not used to make a light bulb. Light bulbs are typically made of glass or other transparent materials, with a filament made of tungsten or other metals that produce light when heated. Hair is not a suitable material for this purpose.
Is a metal a source of light?
Answer No, not in itself. Metal can be used as a component in artificial light sources, and metal can be used to reflect light, but metal does not make light. Answer Metals, when heated to a certain temperature, can emit light. For example, Light bulbs have filaments of Tungsten in them. Electricity flowing through the Tungsten heats it up and it emits light.
What is the filament purpose?
If you are asking about a light bulb, the threadlike conductor, often of tungsten, that is heated to incandescence by the passage of current
How does the light bulb help?
If you are asking for operation for old light bulbs. Then there is a tungsten filament is provided in the bulb which get heated on supplying power and emmits light and heat.
What are so uses of the element tungsten?
its used in light bulbs and high power tools that are used in high heated areas.
How is eletrical energy converted in light energy?
In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light.In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels.

Why are light bulbs made of tungsten?
Tungsten is a highly densed energy solid metal whose atoms collide continuosly when heated thereby emiting light of different frequencies visible.
A gas heated to millions of degrees would emit?
A gas heated to millions of degrees would emit X-rays.
What are three deficiencies of the wave model of light related to lights interaction with matter?
The wave model of light can not explain why heated objects emit only certain frequencies of light at a given temperature, why some metals emit electrons when light of a certain frequency is shone upon them, and it cannot explain the emission of different wavelengths from the different colors when an object (iron for example) is heated
Is an tungsten light the most efficient light?
What is more efficient a tungsten light or an incandescent light?
Which material which produce light operate with heat?
Incandescent light bulbs are made using a tungsten filament, they are heated to a temperature of over 2500 degrees celcius, or 4500 degrees fahrenheit.
Which element is used in light bulbs as the filament?
Generally, tungsten.
Do light bulbs emit light or suck dark?
Light bulbs emit light.
