Green House Effect

Green house means a building made of glass, with heat and humidity regulated by plants. Atmosphere, like glass some of the long wave radiation emitted by earth and radiates the energy back to the earth. A green house is that body which allows the short wavelength incoming solar radiation to come in, but does not […]

Biodegradation : naturally catalyzed change of a natural compound’s structure

Nonetheless, this alteration can be through various metabolic pathways and does not as a matter of course mean a decrease in harmfulness. Mineralization, one sort of biodegradation, is characterized as the change of a natural substance to its inorganic constituents, rendering the first compound safe. Change is characterized as any metabolically-affected change in the substance […]

Coordination Compounds

Effective Atomic Number (EAN) Rule- Professor N.V. Sidgwick of Oxford University applied the electronic theory of valence proposed by Lewis in 1916 to Werner’s complexes. Lewis had proposed that a covalent bond is formed due to sharing of a pair of electrons between two atoms ,, each atom usually contributing one electron . Sidgwick observed […]

Acids and Bases

Solvent System Theory: An acid is a substance which increases the concentration of the cation obtained by autoionisation of the solvent, and bases are the substances which increase the concentration of the anion of the solvent. If the solvent is represented by AB which gives A+ and B- ions hten , like water , the […]

LIGHT

Light, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metre to radio waves measured in metres. Within that broad spectrum the wavelengths visible to humans occupy a very narrow band, from about […]

Michelson Interferometer

The Michelson interferometer is a common configuration for optical interferometry and was invented by Albert Abraham Michelson. Using a beamsplitter, a light source is split into two arms. Each of those is reflected back toward the beamsplitter which then combines their amplitudes interferometrically A laser falls on a beam splitter, which allows half of the […]

Reflection of Light

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. In the diagram at left, a light ray PO strikes a vertical mirror at point O, […]
