diffraction noun. Diffraction is defined as a process by which light waves break up into dark and light bands or into the colors of the spectrum. Light passing through a narrow opening in the blinds, causing bright and dark shadows and patterns to fall across the floor is an example of defraction.iffraction-Computer Definition. The process by which the propagation of radiant waveforms or light waves is modified as those waves encounter an obstacle or discontinuity, or exit one medium and enter another. Some of the waves deviate from their paths, i.e., bend, by diffraction.

Heterochromia iridum Heterochromia of the eye (heterochromia iridis or heterochromia iridum) is of three kinds. In complete heterochromia, one iris is a different color from the other. In sectoral heterochromia, part of one iris is a different color from its remainder and finally in central heterochromia there are spikes of different colors radiating from the pupil.

Monochromacy For monochromacy as a color blind disease in humans, see achromatopsia. Monochromacy (mono meaning one and chromo color) is, among animals, the condition of possessing only one type of cone cell for color vision, which results in a monochromatic-like (in most cases black and white) vision. Organisms with monochromacy are called monochromats.

4.2.1 Circular dichroism spectroscopy Circular dichroism (CD) spectroscopy is a form of light absorption spectroscopy that measures the difference in absorbance of right- and left-circularly polarized light (rather than the commonly used absorbance of isotropic light) by a substance.

dispersion Medical Definition of DISPERSION. 1. : the act or process of dispersing: the state of being dispersed. 2. : the separation of light into colors by refraction or diffraction with formation of a spectrum; also: the separation of radiation into components in accordance with some varying characteristic (as energy). 3.. : the scattering of the values of a frequency distribution from an average. 4. : the separation of light into colors by refraction or diffraction with formation of a spectrum; also: the separation of radiation into components in accordance with some varying characteristic (as energy).

Potassium dichromate Potassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health.otassium dichromate is usually prepared by the reaction of potassium chloride on sodium dichromate. Alternatively, it can be obtained from potassium chromate by roasting chrome ore with potassium hydroxide.

Disseminated intravascular coagulation What Is Disseminated Intravascular Coagulation? Disseminated intravascular coagulation (ko-ag-u-LA-shun), or DIC, is a condition in which blood clots form throughout the body's small blood vessels. These blood clots can reduce or block blood flow through the blood vessels, which can damage the body's organs.

Herpes Testing PCR testing is preferred if encephalitis or neonatal herpes are suspected. 1  Herpes culture—a sample of fluid is collected via swab from an open sore and inoculated into cells that allow the virus to grow. Once the virus is detected, it can be further identified as HSV-1 or HSV-2, which may be useful for prognosis.

Heterochromia Iridis What is heterochromia iridis? Heterochromia iridis is a condition in which the iris in one eye has a different color than the iris of the other eye. The iris is the tissue of the eye that surrounds the pupil and imparts a color, whether green, blue, brown, hazel, grey, or other, to the eye.

4.2.1 Circular dichroism spectroscopy Historically, ellipticity is the unit of circular dichroism and is defined as the tangent of the ratio of the minor to major elliptical axis. Axial ratios of 1:100 will then result in an ellipticity of 0.57 degrees. Modern CD instruments are capable of millidegree precision.

bio 111 chapter 11 hw2 Nondisjunction is the failure of homologous chromosomes to separate during meiosis I, or the failure of sister chromatids to separate during meiosis II or mitosis. As a result, both homologous chromosomes or both sister chromatids migrate to the same pole of the cell. This produces daughter cells with an imbalance of chromosomes.
