It is simple really, i am studying this at the moment and the uv light can identfy water marks such as the queens head and the watermark at the top of a bank note. . . it emits 345 nanometres of light.

Is Dimethylformamide DMF suitable for UV spectroscopy detection?
Yes
What is difference between an HPLC UV detector and a fluorescence detector?
flourescence is more sensetive than UV detection
What are the UV active inactive compound?
The difference between UV active and inactive compounds is the pi orbitals. Compounds with more pi orbitals are more UV active than those without. Aromatic compounds are generally UV active.
What color is carotene under a UV light?
Carotene will fluoresce in UV light, but the "colour" of the fluorescence is infra red and cannot been seen by the human eye.
What is an essential condition for the reaction of bromine with ethane?
UV Light

Is UV light the same as fluorescent light?
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.
What is the fluid called that you pour into your car radiator to check if the head gasket has gone?
UV (Ultra Violet) Detection Dye. You will also need a UV black light and special glasses to detect leaks when you use this dye.
UV organ?
An organ in some animals that allows for the detection of ultraviolet radiation, such as the UV receptors in some birds.
What is difference between an HPLC UV detector and a fluorescence detector?
flourescence is more sensetive than UV detection
Are UV light and UV rays the same thing?
Yes, UV light and UV rays are the same thing, light emit "rays."
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.
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.
What light is responsible for growth in plants?
Any light that contains or gives off UV rays. (Light bulbs don't work)
What is a reason to not avoid UV radiation?
There are at least four good reasons not to avoid UV radiation. One of these is when it is used to kill germs. Another use is for "curing". This is what the dentist does when he puts a UV light into your mouth, to cure the bonding material. A third use is to detect counterfeit paper money. You may see a cashier put a bill under a UV lamp to check its authenticity. And the last of the four that I will supply is when they aim a UV light at your hand or arm to check to see if you are allowed to reenter a venue!
