The UV light is different to that of fluorescent light. The UV originates from the sun. The latter one does not.
No, it is not. UV is different.

Does a fluorescent bulb specificaly phosphorus reflects ultraviolet radiation.?
There is no phosphorus in a fluorescent lamp, the coating is a compound called phosphor.phosphorus is an element that burns.phosphor is a compound that when excited by an electron beam, UV light, or x-rays glows in visible light.A fluorescent lamp is a mercury vapor UV (aka black light) lamp with a phosphor coating on the inside of the lamp tube to turn the invisible UV light to visible light.
Can you get a sunburn or a tan by sitting next to a fluorescent light?
It would probably takes weeks to get enough UV exposure from a regular white light fluorescent bulb if any.
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is?
actually, the rare-earth phosphors lining the tube.
What is the difference between uranium Marbles and marbles?
Uranium marbles contain up to 3 % uranium; these marbles are fluorescent under an UV light.
Why tube light glowing white colour?
Mercury is present inside the tube light.When we give supply to the tube light the mercury vapours excites and it produces uv radiation which then strikes the fluorescent material and produces light. Therefore it is called fluorescent light.
What is a fluorescent uranium salt?
A salt which become fluorescent when is irradiated with UV radiations from a UV lamp.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."

Which material lines the tubes of fluorescent lights and glows when exposed to UV light?
Phosphor.

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.
How does the fluorescent light bulb work?
ionized mercury vapor emits UV light.phosphor coating on inside of tube absorbs UV light and emits visible light.visible leaves tube.
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is?
actually, the rare-earth phosphors lining the tube.
How does a compact fluorescent light bulb work?
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
How do Plant light bulbs work?
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
What are the energy transformations of a fluorescent light bulb?
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
Why do fluorescent light glow when turned off?
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
