Fractionary :: Fractionary (a.) Fractional.

Grating :: Grating (n.) A system of close equidistant and parallel lines lines or bars, especially lines ruled on a polished surface, used for producing spectra by diffraction; -- called also diffraction grating..

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

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

Uniaxial :: Uniaxial (a.) Having but one optic axis, or line of no double refraction..

Stereoscopic :: Stereoscope (n.) An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer..

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

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..

Fringe :: Fringe (n.) One of a number of light or dark bands, produced by the interference of light; a diffraction band; -- called also interference fringe..

Denominator :: Denominator (n.) That part of any expression under a fractional form which is situated below the horizontal line signifying division.

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..

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..

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

Algorithm :: Algorithm (n.) The art of calculating with any species of notation; as, the algorithms of fractions, proportions, surds, etc..

Reduce :: Reduce (n.) To change the form of a quantity or expression without altering its value; as, to reduce fractions to their lowest terms, to a common denominator, etc..

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

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

Refraction :: Refraction (n.) The correction which is to be deducted from the apparent altitude of a heavenly body on account of atmospheric refraction, in order to obtain the true altitude..

Reciprocal :: Reciprocal (n.) The quotient arising from dividing unity by any quantity; thus, / is the reciprocal of 4; 1/(a +b) is the reciprocal of a + b. The reciprocal of a fraction is the fraction inverted, or the denominator divided by the numerator..
