refimprove date July 2008 merge UV completion date October 2010 In physics , an ultraviolet divergence is a situation in which an integral , for example a Feynman diagram , diverges because of contributions of objects with very high energy approaching infinity , or, equivalently, because of physical phenomena at very short distances. An infinite answer to a question that should have a finite answer is a potential problem. The ultraviolet UV divergences are often unphysical effects that can be removed by regularization physics regularization and renormalization . If they cannot be removed, they imply that the theory is not perturbative ly well defined at very short distances. The name comes from the earliest example of such a divergence, the ultraviolet catastrophe in understanding blackbody radiation . According to then current theory of radiation , in this case, light , the quantity of energy released at any specific wavelength should increase with decreasing wavelength that is, there should be considerably more ultraviolet light released from a blackbody radiator than infrared light . Measurements showed the opposite the most energy was released at wavelengths between the two extremes, which suggested classic mechanics simply didn t describe the phenomenon correctly. This problem led to the development of quantum mechanics . The success of the attack on the original ultraviolet catastrophe has led to the technique being widely applied in modern physics. A similar problem applying quantum field theory to electromagnetism was famously solved through the use of renormalization ... standard model of particle physics .

Image blackbody lg.png thumb 303px The Ultraviolet catastrophe is the error at short wavelengths in the Rayleigh Jeans law depicted as classical theory in the graph for the energy emitted by an ideal black body. The error, much more pronounced for short wavelengths, is the difference between the black curve the wrong curve predicted by the Rayleigh Jeans law and the blue curve the correct curve predicted by Planck s law . The ultraviolet catastrophe , also called the Rayleigh Jeans catastrophe , was a prediction of late 19th century early 20th century classical physics that an ideal black body at thermodynamic equilibrium thermal equilibrium will emit radiation with infinite power. The term ultraviolet catastrophe was first used in 1911 by Paul Ehrenfest , although the concept goes back to 1900 with the first derivation of the math lambda 4 math dependence of the Rayleigh Jeans law the word ultraviolet refers to the fact that the problem appears in the short wavelength region of the electromagnetic spectrum . Since the first appearance of the term, it has also been used for other predictions of a similar nature, as in quantum electrodynamics and such cases as ultraviolet divergence .

Extreme ultraviolet radiation EUV or XUV is high energy ultraviolet radiation, generally defined to be electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelength s from 120 nm down to 10 nm, and therefore by the Planck Einstein equation having photon s with energies from 10 Electron volt eV up to 124 eV corresponding to 124 nanometer nm to 10 nm respectively . EUV is naturally generated by the solar corona and artificially by plasma physics plasma and Synchrotron light source synchrotron light sources. Its main uses are photoelectron spectroscopy , Extreme ultraviolet Imaging Telescope solar imaging , and EUVL lithography . In air , EUV is the most highly Absorption electromagnetic radiation absorbed component of the electromagnetic spectrum, requiring vacuum high vacuum for transmission. EUV generation Neutral atoms or condensed matter cannot emit EUV radiation. Ionization must take place first.

Refimprove date July 2011 The ultraviolet index or UV Index is an international standard measurement of the strength of the ultraviolet UV radiation from the sun at a particular place on a particular day. It is a scale primarily used in daily forecasts aimed at the general public. Its purpose is to help people to effectively protect themselves from UV light, of which excessive exposure causes sunburn s, human eye eye damage such as cataract s, skin aging, and skin cancer see the section Ultraviolet Human health related effects of UV radiation health effects of ultraviolet light . Public health organizations recommend that people protect themselves for example, by applying sunscreen to the skin and wearing a hat when the UV index is 3 or higher see the table below for complete recommendations. Description The UV index is a linear scale, with higher values representing the risk level of skin damage due to UV exposure. An index of 0 corresponds to zero UV irradiation, as is essentially the case at nighttime. While an index of 10 corresponds roughly to midday sun and a clear sky, indices greater than 11 are quite common in the southern hemisphere where the ozone depletion Ozone layer is depleted . The numbers are related to the amount of UV radiation reaching the surface of the earth , measured in Watt W Square metre m sup 2 sup , but the relationship is not simple see below for definition because UV power is spread unevenly over a spectrum of wavelengths the shorter wavelengths are much more damaging. By weighting their effect the index aims to create a number that cannot be expressed in physical units, but is a good indication of likely skin damage.

The article examines the connection between natural ultraviolet light UV radiation and the incidence of cancer in human beings. The connection between UV radiation and cancer is well known to scientists, and what is debated by public policy advocates is the role of ozone . Some researchers have claimed that Ultraviolet radiation levels are or were increasing at an alarming level. They concluded that cancer rates would go up accordingly, unless emissions suspected of reducing the protective effect of atmospheric ozone were banned. In 1993, J B Kerr and C T McElroy published Evidence for large upward trends of ultraviolet B radiation linked to ozone depletion Science 262 1032 . This was disputed by P J Michaels et al. Science 264 1342 but Kerr and McElroy re affirmed their original findings Science 264 1342 . Ultraviolet Radiation UV radiation is part of the light spectrum that ranges from the earth to the sun. UV rays have shorter wavelengths than visible light making then invisible to the human eye. However, some insects are abl to see UV rays.It is called Ultraviolet light because it s electromagnetic ... Types of Ultraviolet Light There are three different types of Ultraviolet light UVA, UVB and UVC UVA Ultraviolet A light has the longest wavelengths.

Ultraviolet photoelectron spectroscopy UPS refers to the measurement of kinetic energy spectroscopy spectra of photoelectric effect photoelectrons emitted by molecules which have absorbed ultraviolet photons, in order to determine molecular energy levels in the valence region. Basic Theory If Einstein s photoelectric law is applied to a free molecule, the kinetic energy math E K math of an emitted photoelectron is given by math E K h nu I , math , where h is Planck s constant , is the frequency of the ionizing light, and I is an ionization energy corresponding to the energy of an occupied molecular orbital . History Prior to 1960, virtually all measurements of photoelectron kinetic energies were for electrons emitted from metals and other solid surfaces. About 1956 Kai Siegbahn developed X ray photoelectron spectroscopy XPS for surface chemical analysis. This method uses x ray sources to study energy levels of atomic core electrons , and at the time had an energy resolution of about 1 eV electronvolt . ref Carlson T.A., Photoelectron and Auger Spectroscopy Plenum Press, 1975 ISBN 0306339013 ref The ultraviolet method UPS was developed to study the photoelectron spectra of free molecules in the gas phase by David W. Turner , a physical chemist at Imperial College in London and then at Oxford University , in a series of publications from 1962 to 1967. ref Rabalais J.W. Principles of Ultraviolet Photoelectron Spectroscopy Wiley 1977 ISBN 0471702854 ref ref Turner D. W. Molecular Photoelectron Spectroscopy Wiley, 1970 ref As a photon source, he used a helium discharge lamp which emits a wavelength of 58.4 nm corresponding to an energy of 21.2 eV in the vacuum ultraviolet region. With this source Turner s group obtained an energy resolution of 0.02 eV. Turner referred to the method as molecular photoelectron spectroscopy , now usually Ultraviolet photoelectron spectroscopy or UPS. As compared to XPS, UPS is limited to energy levels of valence electrons , but measures ... more details

Orphan date March 2012 Context date October 2009 Ultraviolet light spans a narrow range of wavelengths of the EMR spectrum http en.wikipedia.org wiki Ultraviolet Subtypes Specific UV absorbance SUVA wavelengths have analytical uses in providing metrics to measure the aromatic character of dissolved organic matter ref Bourbonniere, 2009 ref by detecting density of electron cloud conjugation. To derive SUVA, first, UVC light at 254 nanometers nm , or 280 nm, ref Bourbonniere, 2009 Holl et al., 2009 ref is measured in units of absorbance per meter of path length, often the sample must be diluted with Ultrapure Water as absorbance can be very high. ref Chantigny et al., 2008 ref As increasing dissolved organic carbon concentration increases absorbance in the UV range, the UV light has to be normalized to the concentration of dissolved organic carbon in mg per L to ascertain differences in the aromatic quality of the water. Aromatic character is used in the study of dissolved organic matter, from mineral soils, or organic soils, to determine the whether dissolved organic carbon in the water is labile, a ready source of energy, or is from a relatively old source of carbon recalcitrant . Measures of water purity often rely on measuring turbidity , not aromaticity. References Reflist Sources Bourbonniree, Richard A. 2009. Peat Water Chemistry.
