Do bulbs give off light, or suck in dark?

Answer 1

Neither, they produce armies of tiny glowing wariiors who beat back the shadow monsters and clear their dingy corpses from the floor so quickly that you never see it happen.

Answer 2

Light bulbs work on a very simple principle. When metal is heated, it glows! The only problem is that it has to be heated up a lot.

Electricity comes into a light bulb via a hot wire connected to a tab on the base of the bulb. Inside the bulb the electricity goes through a wire leading to a piece of tungsten. The tungsten is very thin and coiled to maximize resistance in the wire. When electricity meets resistance, it heats up the resistor.

The tungsten gets to a temperature of about 4,500 degrees Fareinheit. This causes it to get white hot. It glows, and glows quite brightly. Tungsten is used because it has a very high melting point.

The tungsten is encased in a bulb for good reason. Not only does it protect people and objects from the hot tungsten, it also keeps oxygen away from the hot metal, which would make it immediately burn up. The bulb is usually filled with a low pressure, inert gas such as argon.

After the electricity has made its way through the tungsten filament, it goes down another wire and out of the bulb via the metal portion at the side of the socket. It goes into the fixture and out a white wire.

Answer 3

A fully functioning light bulb gives off photons and electro-magnetic
energy. That is, it changes energy from electricity to light and heat.

Darkness, in itself, cannot change the energy state of anything.
You cannot "add darkness" (other than by introducing an object
to block light) - therefore, there is no such thing as "sucking in
dark".

You can, perhaps, make an analogy between "darkness" and
something else, such as a black hole, to make
counter-arguments, but the mere absence of light (vs. a lot
of gravity) is not an active energy element.

Answer 4

They give off light because it is impossible to "suck in" dark as darkness is only wherever light cannot reach and illuminate.

I could go into the physics of it, but I'll be here forever, as I am a crazed physicist student who loves to ramble to the point that only I understand.

Answer 5

I'm pretty sure that a bulb gives off light

Answer 6

bulbs use a catostrophic process to create a wave field that is called emission, this creates a counter environment to the faster less dense energy field represented by the term darkness relative states of interaction is permissitivity allowance

Answer 7

It gives off light.

Answer 8

They don't do either, really. Incandescent or flourescent 'bulbs' emit light rays which energise any surface the light rays hit and reflect appropriate colours to the eye. PROVIDED THE EYES ARE OPEN OF COURSE.

Answer 9

Light bulds give off light energy, due to the heatign effect on the filament.

Answer 10

A bulb generates light by converting heat energy to light through a process called incandescence. Electricity passes through the tungsten filament, which heats up to about 2.5k celsius at which point it becomes white hot and emits visible light (as well as infrared heat).

Answer 11

Neither.... bulbs grow into beautiful flowers which reflect certain parts of the light spectrum depending on their genus.
