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.

What is barium aluminate?
Barium aluminate is a chemical compound with the formula BaAl2O4. It is a white crystalline solid that can be used as a phosphor material in applications such as fluorescent lighting and in the preparation of ceramics. Barium aluminate emits a bright green light when exposed to ultraviolet radiation.
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.
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.
What is transmitted radiation?
Transmitted radiation refers to the portion of radiation that passes through a material without being absorbed or scattered. This can include various types of radiation such as light, x-rays, or gamma rays. The amount of transmitted radiation depends on the material's composition and thickness.
How does aluminum block ultraviolet light rays?
Aluminum is a highly reflective material that can reflect most of the ultraviolet light rays that come in contact with it. This property helps to protect surfaces coated with aluminum from the damaging effects of UV radiation.
What does fluorescent material do when exposed to ultraviolet radiation?
Fluorescent material absorbs ultraviolet radiation and re-emits it at longer visible wavelengths, producing a glowing effect. This phenomenon is called fluorescence, where the material appears to radiate light of a different color than the ultraviolet light initially absorbed.
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.
What kind of material lines the tubes of fluorescent lights and glows when exposed to UV light?
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.
Does fluorescent material glow under infrared light?
No, fluorescent materials typically do not glow under infrared light. Fluorescent materials absorb ultraviolet or visible light and then re-emit light at a longer wavelength, usually in the visible range. Infrared light is outside this range and does not stimulate fluorescence in these materials.
Where is ultraviolet radiation used in technology?
Ultraviolet radiation is used in technology for applications such as UV sterilization of water and surfaces, fluorescent lighting, UV curing of inks and coatings, and in UV spectroscopy for material analysis. It is also utilized in medical devices for treatments like phototherapy and in UV lithography for producing microelectronics.
What are fluorescent materials illuminated with?
Fluorescent materials are typically illuminated with ultraviolet (UV) light. When UV light is absorbed by the fluorescent material, it re-emits visible light at a longer wavelength, creating the characteristic fluorescence.
What is barium aluminate?
Barium aluminate is a chemical compound with the formula BaAl2O4. It is a white crystalline solid that can be used as a phosphor material in applications such as fluorescent lighting and in the preparation of ceramics. Barium aluminate emits a bright green light when exposed to ultraviolet radiation.
What material lines the tubes of fluorescent lights and glows when exposed to us light?
The interior of fluorescent light tubes are coated with a phosphor material. When this phosphor material is excited by ultraviolet light produced by the electric current passing through the tube, it emits visible light, creating the glow that we see.
Which material lines the tubes of fluorescent lights and glows when exposed to UV light?
The material lining the tubes of fluorescent lights is called a phosphor coating. This coating is designed to emit visible light when excited by ultraviolet (UV) light produced by the electrical discharge within the tube.
What material lines the tubes of fluorescent lights and glows to UV Light?
Phosphor coating lines the inside of fluorescent light tubes. When the gas inside the tube is excited by electrical current, it emits ultraviolet (UV) light. The phosphor coating then absorbs the UV light and re-emits it as visible light, creating the glow from the fluorescent 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.
Is a ultraviolet wave a mechanical wave?
A mechanical wave is describing something in motion and has a force to do something. An ultra violet is a type of radiation that increases melnin in the skin. Hope this helped!! :p
