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.

When are the electrons emitted from a conductor?
>bombarded by high-speed electronsThat's like saying "water comes out of a pipe when water is poured into the pipe" Conductors don't EMIT electrons (any more than any material), but they allow electrons to flow freely within themselves. That is called a current.On that note, a current flows through a conductor when it is moved through a magnetic field. This is how generators work.Any material can be made to emit electrons by adding electrons to it. That's like saying a full cup will emit water if more water is added to it.ACTUALLY they are emitted. look it up.When it is heated hence those electrons are named as thermions and emission is known as thermionic emission.When light falls on it electrons are emitted. This phenomenon is known as photo electric emission.
How does electricity produced lighting?
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.

What is the light amplification by stimulated emission of radiation?
That is the original meaning for LASER. Light is increased in magnitude by increasing the number of electrons jumping into a lower energy state The light emitted from this process is concentrated and focused
What ejects electrons?
Electrons may be ejected as Beta particles from an atom undergoing radioactive decay. Electrons may also be ejected in high-energy particle collisions such as those produced in a cyclotron. Electrons may also be displaced from an atom by extremes of high temperature when a plasma is formed, by thermionic emission; or by light, during the interaction with a photon of sufficient energy.
What is the study of the release of electrons by light called?
Photo emission.
What type of spectrum does an incandescent light produce?
There are no bright lines and no dark lines in the spectrum, incandescent light has a continuous spectrum with all visible colors present
What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect

What is incandescent light bulb?
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.

When the electrons of an excited atom fall back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
When electrons of an excited atom falls back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
What is a light dependent resister?
As light falls on the conductor then emission of electrons would increase the conductivity and so its resistivity decreases. Such a conductor is known as light dependent resistor.
How does emission spectrum looks like?
it is a set of lines corresponding to photon emission wavelengths.
Could incandescent light be used for a fiber optic transmitter?
Incandescent light cannot be used for a fiber optic transmitter. This is because incandescent light is too slow for such a transmitter.
