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

Integer :: Integer (n.) A complete entity; a whole number, in contradistinction to a fraction or a mixed number..

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..

Breach :: Breach (n.) Specifically: A breaking or infraction of a law, or of any obligation or tie; violation; non-fulfillment; as, a breach of contract; a breach of promise..

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

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

Refractor :: Refractor (n.) A refracting telescope, in which the image to be viewed is formed by the refraction of light in passing through a convex lens..

Diacaustic :: Diacaustic (n.) That which burns by refraction, as a double convex lens, or the sun's rays concentrated by such a lens, sometimes used as a cautery..

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..

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

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

Eriometer :: Eriometer (n.) An instrument for measuring the diameters of minute particles or fibers, from the size of the colored rings produced by the diffraction of the light in which the objects are viewed..

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..

Parabola :: Parabola (n.) One of a group of curves defined by the equation y = axn where n is a positive whole number or a positive fraction. For the cubical parabola n = 3; for the semicubical parabola n = /. See under Cubical, and Semicubical. The parabolas have infinite branches, but no rectilineal asymptotes..

Halo :: Halo (n.) A luminous circle, usually prismatically colored, round the sun or moon, and supposed to be caused by the refraction of light through crystals of ice in the atmosphere. Connected with halos there are often white bands, crosses, or arches, resulting from the same atmospheric conditions..

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..

Rainbow :: Rainbow (n.) A bow or arch exhibiting, in concentric bands, the several colors of the spectrum, and formed in the part of the hemisphere opposite to the sun by the refraction and reflection of the sun's rays in drops of falling rain..

Refraction :: Refraction (n.) The change in the direction of ray of light, heat, or the like, when it enters obliquely a medium of a different density from that through which it has previously moved..

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