Extract of sample "Visible Light, X-rays and UV Rays"

Download file to see previous pages  Visible light is emitted during the process of transition of atoms. Visible light can be detected by photographic emulsion, photosensitive cells, and eyes. The light helps us in vision but its users do not end here, it is utilized in communication as well. Communication with the help of visible light is known as VLC (Visible Light Communication). VLC uses LED or simple fluorescent lamps to transmit signals to long distances. These signals are detected and received by special electronic devices which contain diodes. The diodes, in turn, transform the light signals to electrical pulses. A.G. Bell was the first one to demonstrate this idea through his Photophone. The use of LED light was started in 2003. Since visible light has a negligible effect on our eyes when compared to other rays it is the best option for such a communication system. According to an article in Journals of Materials Chemistry, some researchers at the University of Illinois have come up with a disinfecting process for which previously harmful UV rays had to be used. This disinfecting process uses visible light to destroy bacteria and viruses. For this, the researchers used a nitrogen-doped titanium-oxide matrix which had had palladium nanoparticles which allows hydroxyl ions to kill bacteria and viruses. Soon enough, with greater advancement, X-rays were used to treat tuberculosis, tonsils and even cancer. Thus the branch of Radiology had grown manifolds and is still growing because of the chance discovery of X-rays.  The properties of X-rays are so varied that an entire branch namely X-ray optics has been developed to study everything about these rays.

Inelastic scatttering of neutrons or x rays by phonons

...?Inelastic Scattering of Neutrons or X rays by Phonons 519208) Introduction Phonons define the thermal and electrical properties of different materials. These are defined by the degrees of freedom that are imparted in their lattice vibrations. Inelastic scattering of x rays is used in the measure of phonons. (Sinn H et al, 1999) It has been found out that x-ray scattering (RIXS) can be effected by exciting phonons at the L edge and also combining excited electrons at the K-edge. Inelastic Scattering of neutrons The process of x ray scattering involves the double differential cross section process. The...

..., which measures spectral radiance, spectral reflectivity and spectral irradiance of various surfaces. In the portable spectrometer, UV light is used with all the visible light as well as Near Infrared light. (“Observing the Earth”) Visible Rays Aside from its most practical purpose, which is to allow the eyes to view the world, visible light, it is also used for communication, specifically in the “transport [of] huge volumes of information over very large distances” by means of internal reflection in optical fibers (Emery). Moreover, visible red, green and blue false...

Manta rays

...? The manta ray (Manta birostris) is the largest batoid fish in the world. It can reach widths of nearly 30 feet across, and is present in all the world’s oceans. Pectoral fins that have evolved into wing-like shapes allow these magnificent fish to glide effortlessly through the ocean. Although all manta rays are massive, there are several different species that occur around the world, and each one varies slightly in size. Despite its giant appearance, it prefers inshore waters, and only seldom journeys into the depths of the open ocean. This huge ray has an incredibly slow growth rate, which presents a real problem for their struggling population. Interactions with people can be...

Material Engineering and the Production of X-Rays

..., his hand came in contact with the tube one day, and saw shadows of his hand with darker shadows that represented the bones. When he moved his hand, the shadow on the screen also moved. He named the shadow the first x-ray picture (Lewin, Paradijs and Heuvel 373). X-ray works in a unique way. As the wavelengths of light diminish, they augment in terms of the energy that is produced. X-rays have lesser wavelengths, which cause higher energy compared to ultraviolet waves. This is the reason as to why professionals consider X-rays with respect to the energy they produce rather than their...

Comparison of George Orwell's 1984 and Bradbury Rays Fahrenheit 451

...Human beings are deceptive, relations are not trustworthy and truth means nothing big to anyone anymore. These are a few lessons which we learn from two of the most brilliantly written novels of their times, which include George Orwell’s 1984 and Bradbury Ray’s Fahrenheit 451, with the main protagonist of 1984 being Winston Smith and of Fahrenheit 451 being Montag. Both novels revolve around various cases of deception where Winston Smith, who was a low ranking member of a London based ruling party, along with his love interest Julia, believed O’Brien who was deceiving Winston. Winston Smith is not happy with the way his party functions as they lack freedom and the party prohibits freedom of expression along with the...

UV Light: Patterns in Nature

...Patterns in Nature Ultraviolet light commonly referred to as UV light is a form of an electromagnetic radiation not visible to the human eye because of a shorter wavelength as compared to the light visible to humans. This light is comparatively stronger carrying more energy than normal light and can rupture the chemical bond in atoms or molecules and hence damaging the initial chemistry of the substance that has been exposed to it. A feature of UV light is that it causes fluorescence because of which certain materials radiate visible...

Uv/vis

...UV-VS spectroscopy is a concept referring to absorption spectroscopy, usually through the help of light from the visible and adjacent ranges. A qualitative analysis on the performance characteristics of a UV/VIS absorption spectrometer is important in accessing how this apparatus helps in determining the concentration of unknown solutions. In this experiment, the beer lambert law was considered to help in determining the concentration of the unknown solutions. Introduction UV-VS spectroscopy is a concept referring to absorption spectroscopy, usually through the help of light from the visible and adjacent ranges. In this...

The Effects of Leakage Radiation from X-Rays

...that was behind the discovery of X-ray. The paper also reveals the contribution of Heinrich Hertz to the history of radioactivity through the discovery the presence of radio waves. However, it was Henri Becquerel, who conducted further studies on the beneficial effects of radioactive waves. The paper reveals that the work of the two scientists led to the discovery of the possible uses of radioactivity. Madame Curie is credited for having carried out researches that led to the discovery of more uses of radioactivity (Knoll 2010, p. 99). The paper also reveals the contribution of Thomas A. Edison about the use of the most effective calcium tungstate-based option in the radiation process. Hal Gray is...
