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.
Does flame of a gas stove emit light?
yes!because fire is a luminous body
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.

Does a light bulb convert electrical energy to both heat and light energy?
Yes. Heat is radiated as infra-red, a longer wavelength than visible light, but otherwise similar. Incandescent light bulbs with a heated filament emit infra-red light as heat, and only a small part of the emission is visible. Other light bulbs using electrical discharges in neon gas (known as fluorescent bulbs) do not produce as much infra-red, and are more efficient in the conversion of electrical energy into light. If you feel a fluorescent tube you will find it is only warm, but DO NOT feel an incandescent bulb or you will burn your hand, its so hot.
What is the gas Argon used for?
Incandescent light ,
Does the flame of gas stove emit light Explain.?
Yes it emit
What Gas is used in incandescent light bulbs?

Is it true that gas Atoms subjected to electricity emit bright lines of light?
yes, they do emit
Do atoms in an incandescent gas absorb or emit light?
When they exit their exited state. When an atom is bombarded by photons, it will often times absorb the photon. A photon is a unit of energy, so this energy is added to the atom, "extiting" it. However, atoms may only remain in ths excited state for a short period of time, and will eventually release the photon, reemiting it as light, and then the atom will return to its normal state.
Does the red light from glowing neon gas have only one frequency or a mixture of frequencies?
a mixture of frequencies.
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.
Does the flame of a gas stove emit light?
Yes, because fire is a luminous body

What would happen if the light from a star passes through a cool cloud of sodium gas?
The gas absorbs certain frequencies of light, producing an absorption spectrum.
