Useful Words Definitions

Reducer: a substance capable of bringing about the reduction of another substance as it itself is oxidized; used in photography to lessen the density of a negative or print by oxidizing some of the loose silver.

Compaction: an increase in the density of something.

Rarefaction: a decrease in the density of something.

Rarefy: lessen the density or solidity of.

Heavy: of comparatively great physical weight or density.

Demographer: a scientist who studies the growth and density of populations and their vital statistics.

Scintillation: the twinkling of the stars caused when changes in the density of the earth's atmosphere produce uneven refraction of starlight.

Albers-Schonberg Disease: an inherited disorder characterized by an increase in bone density; in severe forms the bone marrow cavity may be obliterated.

Heavy Metal: a metal of relatively high density (specific gravity greater than about 5) or of high relative atomic weight (especially one that is poisonous like mercury or lead).

Big Bang Theory: (cosmology) the theory that the universe originated sometime between ten billion and 20 billion years ago from the cataclysmic explosion of a small volume of matter at extremely high density and temperature.

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.

Gas: the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throughout any container.

Hdl Cholesterol: the cholesterol in high-density lipoproteins; the `good` cholesterol; a high level in the blood is thought to lower the risk of coronary artery disease.

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

Atomic Number 3: Lithium is a chemical element represented by the symbol "Li" on the periodic table. It is a soft, silvery-white metal that belongs to the alkali metal group. Lithium is known for its low density and high reactivity. It has various industrial applications, including use in rechargeable batteries, ceramics, and certain pharmaceuticals. In medicine, lithium is also used as a mood-stabilizing medication to treat bipolar disorder.

Light: (physics) electromagnetic radiation that can produce a visual sensation.

Projector: an optical device for projecting a beam of light.

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

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

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

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

Optically: in an optical manner.

Eye Condition: the condition of the optical properties of the eye.

Prism Spectroscope: an optical instrument for spectrographic analysis.

Periscope: an optical instrument that provides a view of an otherwise obstructed field.

Collimate: adjust the line of sight of (an optical instrument).

Speculum: a mirror (especially one made of polished metal) for use in an optical instrument.

Rock Crystal: a clear quartz used in making electronic and optical equipment.

Cable: a conductor for transmitting electrical or optical signals or electric power.

Range Finder: a measuring instrument (acoustic or optical or electronic) for finding the distance of an object.

Aberration: an optical phenomenon resulting from the failure of a lens or mirror to produce a good image.
