What does fluorescent material do when exposed to ultraviolet radiation?
it absorbs the ultraviolet radiation and gives out visible light
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
Why do some materials glow in ultraviolet - UV - light?
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
Is ultraviolet light visible?
No
Can Humans can perceive ultraviolet light with their eyes?
No. By definition, "ultraviolet" is that which is beyond the visible light - more specifically, beyond the violet part of visible light.
What gives off visible light under an ultraviolet light?
== Fluorescence== Fluorescent objects emit visible light when stimulated by ultraviolet light.

Does fluorescent material glow under infrared light?
No fluorescent material glows under ultraviolet not infrared

How you convert other rays into visual rays?
If you mean how to convert energy (such as from the sun) that is not visible into visible light; the energy (photons) must interact with something that converts them. For example fluorescent materials (those bright "Dayglow" vests that road workers wear so that they will be seen) convert a portion of the ultraviolet (wavelengths of light that are too short and energetic to be seen with our eyes)into visible light. There are some advanced special materials that can convert infra red (wavelengths of light that are too long to be seen with our eyes)into visible but they are uncommon and expensive.
When is a mineral a fluorescent?
when it glows under ultraviolet light.
The fluorescent molecules will shine when exposed to?
ultraviolet light
Is ultraviolet light visible?
No
Is it posible for a fluorescent material to emit radiation the ultraviolet region after observing visible light explain?
not possible, as visible light photons have less energy and ultraviolet photons need more energy. Energy can neither be created nor be destroyed. So by conservation principle ultraviolet photon as they fall on fluorescent material could give out less energetic light photons, but the converse is not possible.
