The main component of an incandescent light bulb is the metal filament (the spiral). The filament is heated up by the AC current, when the lamp is turned on. The heat excites the metal ions so much that they radiate energy in the form of light. The spectrum of the radiation spans from visible (the warm light you can see) to invisible (infrared, which is heat). Heat is really infrared emission, which is still 'light' in physics terms.
What else can I help you with?
Is hot hotter than tepid?
no
Can high pH levels hurt a hot tub?
Not so much the hot tub more like the people in it, the PH levels are for 2 reasons 1 to stop bacteria growing in the hot tub (which is bad for the user not so much the tub) 2 to stop the liquid in the hot tub melting the occupant of the hot tub (melting might be a little strong but serious irritation and sickness can occur if your tub is not properly maintained) Side note: if the PH is way off it could adversely affect parts of the hot tub, but if it's that extreme you will be in for a nasty time if you get in it.
What common items contain argon?
Argon can be found in fluorescent light bulbs, lasers, and some welding applications. It is also used in the production of semiconductor materials and as a gas for protecting materials from oxidation during manufacturing processes.
Why it is difficult to hold a stainless steel containing hot milk?
As the steel is a good conductor of heat, it transport heat easily. The hot milk is hot so the heat in the milk allows the steel to transport it to our hand. We will feel the heat and you will find it difficult to hold a stainless steel containing hot milk( I cannot confirm this answer will be right .Is it what you want? If you want to use it somewhere else rearrange it in your own words)
What element is essential in a light bulb?
In the old style filament lightbulbs it was tungsten (wolfram).
Why doesn't a light bulb become hot when lighted?
Lightbulbs do get hot when lit - even cfl bulbs get a bit hot.
When was Lightbulbs - album - created?
Lightbulbs - album - was created in 2008-09.
Why do you need lightbulbs?
we need light bulbs so we can see in dark rooms.
Why did the steel industry grow so quickly after the civil war?
they used it for lightbulbs
What gas is typically found in lightbulbs?
The gas typically found in lightbulbs is argon.
Why is tungsten used for lightbulbs?
that is because it has a and a high melting point so it does not melt easily when heated.
What are the benefits of using fluorescent lightbulbs compared to traditional incandescent lightbulbs?
Fluorescent lightbulbs are more energy-efficient and last longer than traditional incandescent lightbulbs. They also produce less heat and can help save money on electricity bills in the long run.
What actors and actresses appeared in Lightbulbs - 2011?
The cast of Lightbulbs - 2011 includes: Vyacheslav Andreyenko as Old Man
What are uses of tungsten?
lightbulbs?
How are lightbulbs measured?
Watts
How is krypton used by man?
It is used to fill incandescent lightbulbs, florescent lightbulbs, and bulbs used for photography (flash bulbs)
What light bulbs should you buy?
Fluorecent lightbulbs are recommended, as they are more efficient than incandescent lightbulbs. They also help the enviroment.
