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.

Is glow in the dark material fluorescent?
They are sort of related; however, glow in the dark materials are actually referred to as phosphorescent. The whole idea behind photoluminescence is that a material absorbs radiation (light) and then re-emits it. Phosphorescent materials absorb light, but release it at a much slower rate. Therefore, they absorb light when they are exposed to it, and then continue releasing it after the light source is removed. Fluorescence, on the other hand, is a material that that absorbs ultraviolet radiation (such as light from a black light) and then releases visible light.
What is the need for fluorescent material?
Fluorescent materials are used in illumination, displaying, solid state lasers,light communication,light memory and so on.
Why does the colors of an object look different under a fluorescent lamp from the way it looks under an incandescent lamp?
differences in the color of light will change the color's appearance as it is seen under fluorescent and incandescent. An incandescent lamp, like the sun, produces a spectrum of light in every color in a wide band, broad enough to cover the entire visible spectrum -- and extending past it to many colors that humans can't see. A fluorescent lamp produces a spectrum of light in a few narrower bands of color. That is why a fluorescent lamp is more energy efficient than a incandescent -- the fluorescent lamp doesn't waste energy producing photons that humans can't see. Some materials (such as white paper) reflect all visible colors equally. They look white in almost any kind of light. Other materials absorb some colors more strongly than other colors. They look colored in "white" incandescent light. If we have a material that reflects most colors equally, except for a narrow band of colors, and that band is in the "dark" part of of the fluorescent spectrum -- it will look the same color as white paper. If we have another material that reflects most colors equally, except for a narrow band of colors that is in one of the bands of colors produced by a flourescent lamp -- that material will look even more deeply colored in fluorescent light than in incandescent light.
Do ultraviolet waves travel at the speed of light in a vacuum?
Ultraviolet and visible light waves all travel at the same speed whenever they're all traveling through the same material.
What do conduction and convection do that radiation does notwhat does radiation use instead?
Conduction and convection badly needs material medium but radiation does not need a material medium as an essential one. It could traverse even in free space in the form of electromagnetic waves
What does fluorescent material do when exposed to ultraviolet radiation?
it absorbs the ultraviolet radiation and gives out visible light
Does fluorescent material glow under infrared light?
No fluorescent material glows under ultraviolet not infrared
Difference between fluorescent and phosphorescent material?
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it absorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
The transfer of heat energy to a neighbouring material without contact?
Radiation such as the Sun gives off ultraviolet radiation to burn your skin from 93 million miles away.
The danger of ultraviolet radiation?
It is simple the ozone layer pertects some of the ultraviolet radiation that comes from the sun if you are exposed to much of the sun you can get skin cancer that is the danger of ultraviolet radiation
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.

What is Transmissibility of radiation?
Is how much radiation goes through a material.

How is radiation used in the making of bombs?
The radiation comes from the material used.
What material is anti radiation?
i think its a lead metal its an anti radiation
What are ultraviolet light could be search for?
One the uses of ultraviolet light is to reveal genetic material like blood. Even blood that has been cleaned up is revealed by an ultraviolet light.
