Benzene :: Benzene (n.) A volatile, very inflammable liquid, C6H6, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum..

Refractometer :: Refractometer (n.) A contrivance for exhibiting and measuring the refraction of light.

Prism :: Prism (n.) A transparent body, with usually three rectangular plane faces or sides, and two equal and parallel triangular ends or bases; -- used in experiments on refraction, dispersion, etc..

Catadioptrical :: Catadioptrical (a.) Pertaining to, produced by, or involving, both the reflection and refraction of light; as, a catadioptric light..

Fractional :: Fractional (a.) Relatively small; inconsiderable; insignificant; as, a fractional part of the population..

Inflection :: Inflection (n.) Same as Diffraction.

Refracted :: Refracted (a.) Turned from a direct course by refraction; as, refracted rays of light..

Integral :: Integral (a.) Of, pertaining to, or being, a whole number or undivided quantity; not fractional..

Sexagesimal :: Sexagesimal (n.) A sexagesimal fraction.

Dioptrics :: Dioptrics (n.) The science of the refraction of light; that part of geometrical optics which treats of the laws of the refraction of light in passing from one medium into another, or through different mediums, as air, water, or glass, and esp. through different lenses; -- distinguished from catoptrics, which refers to reflected light..

Diacaustic :: Diacaustic (a.) Pertaining to, or possessing the properties of, a species of caustic curves formed by refraction. See Caustic surface, under Caustic..

Denominator :: Denominator (n.) That number placed below the line in vulgar fractions which shows into how many parts the integer or unit is divided.

Measure :: Measure (n.) A standard of dimension; a fixed unit of quantity or extent; an extent or quantity in the fractions or multiples of which anything is estimated and stated; hence, a rule by which anything is adjusted or judged..

Scrip :: Scrip (n.) Paper fractional currency.

Anaclastics :: Anaclastics (n.) That part of optics which treats of the refraction of light; -- commonly called dioptrics.

Fraction :: Fraction (v. t.) To separate by means of, or to subject to, fractional distillation or crystallization; to fractionate; -- frequently used with out; as, to fraction out a certain grade of oil from pretroleum..

Aphakia :: Aphakia (n.) An anomalous state of refraction caused by the absence of the crystalline lens, as after operations for cataract. The remedy is the use of powerful convex lenses..

Neurine :: Neurine (n.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide..

Fraction :: Fraction (n.) A portion; a fragment.

Fractionate :: Fractionate (v. t.) To separate into different portions or fractions, as in the distillation of liquids..
