Excimer lasers are pulsed gas discharge lasers that produce ultraviolet (UV) light. A chemical reaction with an excimer or an excited dimer is used to power the excimer laser. An excimer can be defined as a heterodimeric or a dimeric molecule that is short-lived, formed from two atom species...
If you have placed a prism in the sun, then you have likely noticed the rainbow effect it produces. This is because white light is a mixture of all the colors of the visible spectrum, and when it passes through a prism, it is separated–or diffracted–into its component colors. This is...
Sunlight is the ideal light source, but even ambient light produces electricity. However, low-light sources like indoor lighting or moonlight won’t generate sufficient wattage for many applications. Solar-powered LCD calculators are a common example of a low-wattage application that runs on ...
Ultraviolet light causes melanocytes to increase their activity in producing melanin. While the light itself does not directly affect the melanocytes,...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
Which has the greater energy; yellow light or green light? What are the colors of the visible spectrum listed in order of increasing wavelength? If an object absorbs all colors but blue, what color would it appear to be? What produces all light energy?
UV printing is a digital printing technique where ultraviolet light is used to instantly dry or cure the ink applied to a surface. Unlike traditional methods that rely on heat, UV printers use high-intensity UV lamps to solidify the ink. This process allows the ink to adhere tightly to the...
The arc emits extremely bright light and ultraviolet radiation, which may damage the eyes. Molten metal splashes and sparks can burn the skin and cause a risk of fire, and the fumes generated in welding can be dangerous when inhaled. These hazards can be avoided, however, by preparing for ...
A germicidal lamp is an electric light that produces ultraviolet C light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoa. It can also be used to produce ozone for water disinfect...
Argon, when lit, is lavender, but with a tiny drop of mercury, produces ultraviolet. Helium produces orange-white, krypton produces greenish-gray, mercury vapor produces a pale blue, and xenon a blue-gray color. Uses Neon colors, when placed in a vacuum tube, emit a brilliant light, ideal...
But it’s a real marvel: The sun warms our planet every day, provides the light by which we see and is necessary for life on Earth. It can also cause cell death and make us blind. It could fit 1.3 million Earths inside its sphere [source: SpaceDaily]. It produces poem-worthy ...
