Florescent lams do ... museums use a tubular UV filter over those bulbs to prevent damage to two-dimensional paper ephemera.
Ultraviolet (UV) light bulbs emit UV rays.
Black lights appear purple because they emit ultraviolet (UV) light, which is not visible to the human eye. However, some materials in the light bulb or coating on the bulb absorb the UV light and re-emit it as visible light, often in the purple range of the spectrum.
the electricity used to power the light bulb emit carbon dioxide
First all you have to do is paint a regular bulb black.
Strictly speaking the moon doesn't emit anything. The moon reflects. And it probably reflects a bit of UV along with the visible light.
No, most lasers emit light at a different frequency than UV.
The input of a light bulb is electricity, which powers the bulb, causing it to emit light as the output.
A black light is a UV emitting bulb. There are other types of UV bulbs, but most have very specific uses, such as: bug lights, tanning bed lamps, drying lamps for lithographic applications and printing, and medical diagnosis. All lamps--incandescent, fluorescent, mercury vapor, tungsten, etc.-- emit some range of UV light, so could be considered UV lamps, but that is not their specific purpose, and the amounts or levels vary widely.
To emit the generated light?
To emit the generated light?
Fluorescent lights use electric current to excite mercury atoms, which emit UV light. The tube part of the light is covered in phosphorescent material, which is excited by the UV light the mercury produces, and emits visible light. The reason they glow is because it takes a while for an excited mercury atom to emit the UV light, and it takes even longer for the excited phosphorescent molecules to emit all of their excess energy and return to their normal energy levels, also called the ground state. The path of the energy is Electricity -> UV light-> Visible light-> your eye
Yes, some light bulbs, such as fluorescent and LED bulbs, can emit small amounts of ultraviolet (UV) radiation. UV radiation is not visible to the human eye but can have potential health risks if exposure is prolonged.
