Ultraviolet lights are made using special lamps that contain a gas such as Mercury, which emits UV radiation when an electric current passes through it. The gas is enclosed in a tube made of quartz or special glass that allows the UV radiation to pass through. When the lamp is turned on, the electricity excites the gas atoms, causing them to release UV light.
no, because ultraviolet rays are just above seeing and with ultraviolet lights, you see a more violet color.
UV lights do not typically produce a significant amount of heat when they are in operation. UV lights are designed to emit ultraviolet radiation, which is not the same as producing heat.
Sunlight, tanning beds, and certain types of insect zappers are common sources of ultraviolet waves in everyday life. UV lights used for sterilization and counterfeit detection also emit ultraviolet waves.
Sources of ultraviolet waves include the sun, tanning beds, black lights, some types of lasers, and certain industrial processes such as welding and mercury vapor lamps. UV lamps used for disinfection and certain medical treatments also emit ultraviolet waves.
Black lights do not reveal the presence of germs. They are used to detect certain substances that fluoresce under ultraviolet light, but they do not specifically indicate the presence of germs.
They are sometimes called "black lights".
yes
Ultraviolet IS light. It comes from the sun. It's why we wear sun screen.

UV refers to the "Ultraviolet". Do you mean the ultraviolet LED lights? Or the natural sun light? You could find details at Wikipedia.

Ultraviolet light is also known as UV light. Ultraviolet light is electromagnetic radiation wavelengths and is emitted in black lights, tanning lamps and sunlight.
Xenon gas is used in ultraviolet lights as a filler gas because it helps the lamp reach higher operating temperatures quickly, which is necessary for the efficient production of ultraviolet radiation. Xenon also improves the stability and performance of the lamp by reducing flickering and extending the lifespan of the bulb.
