When do atoms emit light energy?
Atoms emit light energy for several reasons: Atoms emit visible light most often when an electron moves from an excited state to a less excited state. Atoms accelerating at high rates can emit bremsstrahlung, or breaking radiation. Finally, atomic nuclei in an excited state can decay to less excited states, emitting light energy. This energy usually not visible though, in the X or gamma ray spectrum.
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.

How the electric energy in in bulbs converted to light energy?
The motion of the electrons in the filament creates HEAT. The heat will excite the atoms of the filament until they emit Photons due to the jumping of electrons to higher energy shells.
Why do fluorescent light glow when turned off?
Fluorescent lights use electric current to excite mercury atoms, which emit UV light. The tube part of the light is covered in phosphorescent material, which is excited by the UV light the mercury produces, and emits visible light. The reason they glow is because it takes a while for an excited mercury atom to emit the UV light, and it takes even longer for the excited phosphorescent molecules to emit all of their excess energy and return to their normal energy levels, also called the ground state. The path of the energy is Electricity -> UV light-> Visible light-> your eye
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 are atoms that emit particles and energy from their nuclei?
radioactive
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.
Do atoms only emit visible light?
Yes because it only have light in common?

Does the energy from Sun energise other planets so they can emit light?
No. Planets do not emit light; they can only reflect light from the Sun.

Can a traffic light emit light energy?
Yes. That is why they are called traffic lights.
Why do you know that lithium salts will never emit green light and copper salts will never emit red light?
Because they each have their own level of energy. Green light has more energy than red light.
Atoms may emit light energy when?
protons move to a higher energy level protons move to a lower energy level electrons move to a higher energy level electrons move to a lower energy level
