How does electrical current produce light?
Different kinds of light use different mechanisms. Currently, the technologies used include incandescent lights, fluorescent lights, and LEDs.In an incandescent light (that's the most wasteful light), a current heats up a wire, until it glows.In a fluorescent light, the current excites atoms, i.e., it raises electrons to a higher energy level. When the electrons fall back, they emit light.I believe LEDs work on a similar principle, i.e., exciting the atoms; however, the material is solid instead of a gas.Different kinds of light use different mechanisms.

How is electricity turned into light?
That varies, depending on the technology. In an incandescent light bulb, a wire is heated when electricity passes through it, until it glows. In a fluorescent light bulb, atoms in a gas get into an excited state, and emit light when the electrons fall back to their normal energy level.
What is the strip of material that glows in a light bulb called?
The strip of material that glows inside a light bulb is called the filament. It is usually made of tungsten and emits light when an electric current passes through it, heating it to a high temperature, causing it to glow and produce visible light. The filament is a crucial component in incandescent light bulbs, which have been widely used for many years, although more energy-efficient lighting technologies, such as LED (Light Emitting Diode) bulbs, are becoming increasingly popular
How does a florecent light bulb save energy?
I think you meant "use less energy" rather than "saves less energy"...Incandescent light bulbs generate light by heating a filament until it glows brightly. A great deal of energy is lost as heat and only a little energy is converted to visible light.Fluorescent light bulbs (whether "compact" or not) generate light by exciting the atoms in the phosphor coating on the inside of the bulb. This is more efficient, as there is less heat generated, so less electricity is needed to produce the same amount of light.LED lights are even more efficient than fluorescent, but they are still rather expensive for general lighting.
What is argon's appearance?
it is colourless oderless tasteless and glows
Difference between fluorescent and phosphorescent material?
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it absorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
Does fluorescent material glow under infrared light?
No fluorescent material glows under ultraviolet not infrared
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
When is a mineral a fluorescent?
when it glows under ultraviolet light.
Why diamond glows in dark?
Some diamonds are fluorescent. This means that light enters the stone and the wave length is converted to a longer light wave. Not all diamonds are fluorescent. No diamond will 'glow in the dark' without first being exposed to a light source.
Can light be changed into energy?
Chemical energy (chem-lights and lightning bugs) electricity (through LEDs, fluorescent tubes, neon lights, lasers) and heat (the sun glows from heat, and so do light bulbs)
How do glowing dashboards glows?
There are lights inside it so when you turn it on it glows.

When a fluorescent light bulb glows what state of matter is it?
it is plasma , gas and liquid
What are the best alternatives for CFL's?
Compact Fluorescent Lamp lights are a popular bulb alternative used today. Its advantages include a much longer lifespan that an incandescent, and it glows a more relaxing light towards the eyes.
What are some fluorescent minerals?
If you put them under ultra-violet light it changes color and glows.
What element glows in the dark when previously exposed to light?
Phosphorous
