Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them. Here are some typical lasers and their emission wavelengths (in nanometers): Argon fluoride (UV): 193 Krypton fluoride (UV): 248 Xenon...
And, although UV light has more than enough firepower to make a photocopy, it can be very damaging to our eyes and skin. This is why photocopiers use a plain old incandescent or fluorescent bulb to flash light onto the original document. When the lamp in the copier is turned on, it ...

The CSI may also use luminol and a portable UV light to reveal blood that has been washed off a surface. If there is blood at the scene, there may also be blood spatter patterns. These patterns can reveal the type of weapon that was used -- for instance, a "cast-off pattern" is ...
There is a new bright light shining on Ultraviolet (UV) light. It’s the spectrum of light just beyond the visible range that has several bands of wavelengths.
UV light waves have been proven to inactivate certain types of bacteria, like E. Coli and salmonella, in addition to ethylene gas, a gas that speeds up the rotting process. [source: Science Direct]. By clearing off this bacteria, the BLUE bowl keeps your produce safe and fresh for longer...
ASML's deep ultraviolet lithography systems dive deep into the UV spectrum to print the tiny features that form the basis of the microchip. 阿斯麦的深紫外光刻系统深入紫外光谱,打印构成微芯片基础的微小特征。 DUV is for anything that is low technology, like a toaster or refrigerator or even some...
Understanding Ultraviolet Light Firstly, you cannot determine the effectiveness of anything without completely understanding it. Therefore, we will coverwhat is UV lightand how it works prior to delving deep into the topic. UV light is a form of electromagnetic radiation with wavelengths shorter than...
(Bonus fact: The urine of many rodent species reflects ultraviolet light, which may be why rodents have retained UV vision, unlike other mammals [source: National Geographic].) Read More Testing for Color Blindness Color blindness test plates Dorling Kindersley/Getty Images The kind of color...
4. The new ultraviolet observations were compared with similar observations made in laboratories, where researchers determined how much UV light would be reflected by water versus other material. 5. It is not clear how much international support there is for any potential action against Iran. ...
