17)All-woman BSF bikers create record with Republic Day iniciación; Twitterati beam with pride

India Republic Day -- To indicate Indias 69th Republic Day a grand parade was held from Rajpath in New Delhi like every year after Best Minister Narendra Modi given homage to the nations martyrs by laying a wreath at Amar Jawan Jyoti. But this time around the race fans were in for a splendid big surprise when a newly-formed Border Safety Forces Womens Motor Cycle staff Seema Bhawani made a spectacular debut with their daredevil stunts at the parade. Led through Sub-Inspector Stanzin Noryang the squad performed breathtaking stunts for the audience including a salute to the President! Out of the of sixteen stunts an d acrobatics fish riding side riding faulaad prachand baalay shaktiman bull fighting sapt rishi seema prahari bharat ke mustaid prahari sarhad ke nigheban and flag march pyramid were the highlights. Using 113 women the Seema Bhawani made a phenomenal obtain on 26 350cc Supérieur Enfield motorcycles. While the target audience cheered for them and even presented them a sta

Classification of methods

Image
Spectroscopy is a sufficiently broad field that many sub-disciplines exist, each with numerous implementations of specific spectroscopic techniques. The various implementations and techniques can be classified in several ways. Type of radiative energy edit The types of spectroscopy are distinguished by the type of radiative energy involved in the interaction. In many applications, the spectrum is determined by measuring changes in the intensity or frequency of this energy. The types of radiative energy studied include: Electromagnetic radiation was the first source of energy used for spectroscopic studies. Techniques that employ electromagnetic radiation are typically classified by the wavelength region of the spectrum and include microwave, terahertz, infrared, near-infrared, ultraviolet-visible, x-ray, and gamma spectroscopy. Particles, because of their de Broglie waves, can also be a source of radiative energy. Both electron and neutron spectroscopy are commonly used. For a particl

( April 2016 ) Other types of spectroscopy are distinguished by specific applications or implementations: Acoustic resonance spectroscopy is based on sound waves primarily in the audible and ultrasonic regions. Auger electron spectroscopy is a method used to study surfaces of materials on a micro-scale. It is often used in connection with electron microscopy. Cavity ring-down spectroscopy Circular Dichroism spectroscopy Coherent anti-Stokes Raman spectroscopy is a recent technique that has high sensitivity and powerful applications for in vivo spectroscopy and imaging. Cold vapour atomic fluorescence spectroscopy Correlation spectroscopy encompasses several types of two-dimensional NMR spectroscopy.

History

The history of spectroscopy began with Isaac Newton's optics experiments (1666–1672). According to Andrew Fraknoi and David Morrison, "In 1672, in the first paper that he submitted to the Royal Society, Isaac Newton described an experiment in which he permitted sunlight to pass through a small hole and then through a prism. Newton found that sunlight, which looks white to us, is actually made up of a mixture of all the colors of the rainbow." Newton applied the word "spectrum" to describe the rainbow of colors that combine to form white light and that are revealed when the white light is passed through a prism. Fraknoi and Morrison state that "In 1802, William Hyde Wollaston built an improved spectrometer that included a lens to focus the Sun's spectrum on a screen. Upon use, Wollaston realized that the colors were not spread uniformly, but instead had missing patches of colors, which appeared as dark bands in the spectrum." During the early 1800s,

Spectroscopy

Image
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum; indeed, historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO). Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over as
