CHEMISTRY GLOSSARY
geometrical optics → geometrijska optika
In most cases light can be described as an electromagnetic wave. Geometrical optics is an approximation in which the waves can be represented as straight-line rays. This approximation is valid if the light waves do not meet obstacles comparable in size to the wavelength of radiation.
holography → holografija
Holography is a technique for creating a three-dimensional image of an object by recording the interference pattern between a light beam diffracted from the object and a reference beam. The image can be reconstructed from this pattern by a suitable optical system.
chlorophyll → klorofil
Chlorophyll is a green pigment present in green plants and cyanobacteria. Chlorophyll is essential in the transformation of light energy to chemical energy in photosynthesis. Chlorophyll absorbs light mostly in the blue and red ends of the visible spectrum, and very little in the green wavelengths. That green light is reflected, giving us the leaf colour we see.
Einstein equation → Einsteinova jednadžba
Einstein equation is the mass-energy relationship introduced by Albert Einstein in 1905 in the form E = mc2, where E is a quantity of energy, m its mass, and c is the speed of light. It presents the concept that energy possesses mass.
Einstein, Albert → Einstein, Albert
Albert Einstein (1879-1955) is a German born American physicist, who took Swiss nationality in 1901. A year later he went to work in the Bern patent office. In 1905. he published five enormously influential papers, one on Brownian movement, one on the photoelectric effect, one on the special theory of relativity, and one on energy and inertia (which included the famous expression E = mc2). In 1915 he published the general theory of relativity, concerned mainly with gravitation. In 1921 he was awarded the Nobel Prize. In 1933, as a Jew, Einstein decided to remain in the USA (where he was lecturing), as Hitler had come to power. For the remainder of his life he sought a unified field theory. In 1939 he informed president Roosevelt that an atom bomb was feasible and that. Germany might be able to make one.
electric cell → električni članak
Electric cell (battery) is a device that is capable of changing some form of energy, such as chemical, nuclear or radiant energy, into electricity. A solar cell, for example, consists of a semiconductor junction that converts sunlight directly into electricity. A dry cell battery converts chemical energy into electricity.
light scattering → raspršenje
Light scattering is a type of diffuse reflection. When light strikes a rough surface, small flat areas are almost comparable to the wavelength, so the light scatters.
