What are objects that emit light?
Objects that emit light are usually referred to as incandescent.
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.

As well as light what else does a light bulb produce?
It kinda depends on what kind of bulb incandescent lights use filaments and emit heat, for example
What energy trasnformations occur in a incandescent light bulb?
In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
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 objects that emit light?
Objects that emit light are usually referred to as incandescent.
Which is a better floor lamp - incandescent or fluorescent?
Incandescent floor lamps emit a lower ray of light, therefore you won't get as bright a light shine. A flourescnet light is much brighter. It really depends on where you will put the lamp.
Why does incandescent light not glow on material?
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
What do all incandescent materials have in common to cause them to emit light?
They're hot (above about 800 degrees Kelvin).

Hor are LEDs similar to incandescent light bulb?
They emit light and the use electricity. Apart from that, they have little in common, the way they work is completely different.

What is the difference between floroscent and incandescent?
Incandescent light bulbs contain a metal filament (normally tungsten). When electricity flows through the filament, it gets very hot, causing it to emit light. They are inefficient because most of the electric power goes into heat. Fluorescent light bulbs contain a circuit that increases the voltage of the electricity, which then ionizes mercury vapor. This ionized mercury emits ultraviolet light, which causes a coating on the inside of the glass bulb to glow ("fluoresce). They are more efficient, but many emit an ugly color of light.
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.
What type of star does not emit light?
All stars emit light. However, people are not able to see some stars because of the different type of light the wavelengths produce. +++ Also of course, the received intensity depends on distance. A black hole would be incandescent too, but by its definition the light it creates cannot escape the objects immense gravitation.
Do light bulbs emit light or suck dark?
Light bulbs emit light.
Does technetium emit light?
Technetium doesn't emit light.
