Either the filament or a gas inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.

Why do two incandescent light bulbs glow with different intensities when connected in the same circuit?
When you are wiring two light bulbs in SERIES, you split the voltage to each light bulb in HALF, meaning that it will only glow half the brightness per bulb, but it will only draw the current of one bulb, meaning if the bulbs were connected to a battery, it would last longer to connect them together in series, rather than parallel.
What type of light do glow sticks react to?
Glow sticks are a chemical light.
The power pf light bulbs in Measured in?
The power of light bulbs is measured in
Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?
All the three would glow at the same instant.
How does a lightbulb make light?
It depends which type of bulb you mean... The 'energy saver' ones - are miniature fluorescent bulbs - they have a light-emitting coating on the inside, which is 'stimulated' by mercury vapour created when the power flows through it. The older 'pearl' bulbs work by the resistance of a wire filament inside the bulb causing it to glow as it heats up.
Why do the flimant in light bulbs not have oxygen inside?
because it doesn't let the light glow
What are the light bulbs that use a wire to conduct heat to male it glow?
It might be the energy saving bulbs.
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.
Is argon used in glow sticks?
yes also in light bulbs and lasers!

How does electricity work in light bulbs?
The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
Why do light bulbs glow dull?
(long story short) Because just like you, you grow older than eventually die :)
What bulbs go in a s-10?
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
What happens if three 60 W light bulbs are mistakenly wired in series and connected to a 120 V power supply Assume the light bulbs are rated for single connection to 120 V?
Since the bulbs are in series, each one will have 40 volts across it instead of the 120 volts it was designed for. The bulbs will glow very dimly or not at all.
Does any company make ultra-violet dome light bulbs for vehicles The ones that make white objects glow?
There are literally dozens of UV light manufacturers on the internet that make lights that are powered by 12v DC. Just search for "Ultraviolet light, 12v". Many bulbs can be engineered to fit in a dome light of a vehicle.
What causes incandescent light bulbs to produce light?
The filament in the bulb has a high resistance to the flow of electricity. As electricity passes through it, the filament heats up and begins to glow, giving off the visible light you see.
Why do things glow in the dark?
they absorb light from before and then when it is dark they glow the absorbed light
