Useful Words Definitions


Homochromatic: (of light or other electromagnetic radiation) having only one wavelength.

Action Spectrum: the efficiency with which electromagnetic radiation produces a photochemical reaction plotted as a function of the wavelength of the radiation.

Shiner: something that shines (with emitted or reflected light).

Laser: an acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light.

Absorption Band: a dark band in the spectrum of white light that has been transmitted through a substance that exhibits absorption at selective wavelengths.

Radiography: photography that uses other kinds of radiation than visible light.

Emit: give off, send forth, or discharge; as of light, heat, or radiation, vapor, etc..

Absorbance: (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation.

Radiography: the process of making a radiograph; producing an image on a radiosensitive surface by radiation other than visible light.

Radiogram: a photographic image produced on a radiosensitive surface by radiation other than visible light (especially by X-rays or gamma rays).

Absorptance: a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber.

Mercury-Vapor Lamp: ultraviolet lamp that emits a strong bluish light (rich in ultraviolet radiation) as electric current passes through mercury vapor.

Absorption Spectrum: the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths.

Disappear: become invisible or unnoticeable.

Cancel: remove or make invisible.

Chromaticity: the quality of a color as determined by its dominant wavelength.

Blackout: darkness resulting from the extinction of lights (as in a city invisible to enemy aircraft).

Running Light: light carried by a boat that indicates the boat's direction; vessels at night carry a red light on the port bow and a green light on the starboard bow.

Mephitis: a poisonous or foul smelling gas emitted from the earth.

Photoelectron: an electron that is emitted from an atom or molecule by an incident photon.

Thermion: an electrically charged particle (electron or ion) emitted by a substance at a high temperature.

Absorbefacient: inducing or promoting absorption.

Absorption Unit: a unit for measuring absorption.

Study: a state of deep mental absorption.

Endothermal: (of a chemical reaction or compound) occurring or formed with absorption of heat.

Searchlight: a light source with reflectors that projects a beam of light in a particular direction.

Autism: (psychiatry) an abnormal absorption with the self; marked by communication disorders and short attention span and inability to treat others as people.

Acer Saccharinum: a common North American maple tree; five-lobed leaves are light green above and silvery white beneath; source of hard close-grained but brittle light-brown wood.

Malignant Anaemia: a chronic progressive anemia of older adults; thought to result from a lack of intrinsic factor (a substance secreted by the stomach that is responsible for the absorption of vitamin B12).

Horizontal Combination: absorption into a single firm of several firms involved in the same level of production and sharing resources at that level.
