What do the phosphors inside fluorescent bulbs absorb to create a glow?
Ultraviolet Radiation.
Why ultraviolet spectroscopy is also called quartz spectroscopy?
I'm a bit curious as to who exactly calls it that; I've never heard that term before. At a guess I'd say it's probably because ordinary glass is somewhat opaque to certain frequencies of ultraviolet light, but quartz glass transmits it.
What is quartz used for today?
There are countless uses for quartz. The colorful transparent varieties are polished into gems. Opaque varieties are processed into ornamental items or building materials. Very pure quartz sand deposits are mined for the many items that use silicon, like computer chips.
What bulbs do not have filament And how do they light up?
Flourescent bulbs. They have no filament and they light up. They have argon gas and a small amount of mercury in them. When electricity is added, the argon and mercury atoms get excited and collide against each other and create light. The light is ultraviolet light and if the bulb is not coated inside with phosphorous, you have a black light.
What is the volume of quartz?

What causes a headlight bulb to explode?
too hotIf it's Quartz-Halogen, then remember that the envelope is not made from ordinary glass, but from quartz, which will take the extreme heat generated by these bulbs. If someone has touched the bulb with bare fingers whilst fitting it, then the slightest trace of grease will cause the bulb to shatter when hot.

How are xenon bulbs different from normal light bulbs?
Xenon bulbs are much brighter than regular light bulbs. They are more expensive that normal light bulbs. this is partly because of the cost of xenon gas, but also because of the heat generated by the bulb that requires them to be housed in quartz instead of glass.
How are tanning bed bulbs used?
The bulbs in tanning beds emit ultraviolet (UVA and UVB) radiation. UVA and UVB are the components of sunlight that cause the skin to tan, so the artificial sunlight given off by tanning bed bulbs tans the skin.
Where does the gas in light bulbs come from?
Some light bulbs have gases added to them at the time of manufacture. Noble gases help to keep the electrode material from bonding to the envelope (the dark areas that build up near the ends of an aged fluorescent light bulb are causede by this effect). Otherwise, gases enter a lightbulb's envelope via diffusion through the membrane or along the electrode / envelope interface.
How many watts do big bulbs use?
The usual criteria is that the larger the envelope size of the lamp the larger the wattage of the lamp. The terminology of "big bulbs" suggests that the lamp could be in the range of 400 watts.
What are the main advantages of halogen light?
Halogen lights have many advantages over others. Among these are the clarity of the envelope and the extended life period of the bulb. These bulbs can be used at higher temperatures than other bulbs.
What type of glass is used for light bulbs?
glass with powder coating

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.
Why are ultraviolet lamps used in disinfecting water from drinking fountains instead of ordinary incandescent bulbs?
They emit short wave UV that kills germs and many microorganisms.
