What are objects that emit light?
Objects that emit light are usually referred to as incandescent.
Why does an incandescent light emit light?
Because the filament is extremely hot
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.
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.

What do all incandescent materials have in common to cause them to emit light?
They're hot (above about 800 degrees Kelvin).
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.
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.
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 color are the cooler stars?
Colder stars emit red light. Hot stars emit large amounts of green light with small amount of red and blue light, which balances out to a white color in human eyes.
What is the color of black?
Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light.
Is Black the of color?
Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light.
