Bent backward angularly, as if half-broken; as, a refracted stem or leaf.

Refracted; as, a retrofract stem.

One of the seven colors into which the rays of light divide themselves, when refracted through a glass prism; the color of the clear sky, or a color resembling that, whether lighter or darker; a pigment having such color. Sometimes, poetically, the sky.

caustic remark. Caustic curve (Optics), a curve to which the ray of light, reflected or refracted by another curve, are tangents, the reflecting or refracting curve and the luminous point being in one plane. -- Caustic lime. See under Lime. -- Caustic potash, Caustic soda (Chem.), the solid hydroxides potash, KOH, an…

A curved formed by the consecutive intersections of rays of light refracted through a lens.

Pertaining to the science or doctrine of refracted sounds.

The doctrine of refracted sound; diacoustics.

ncealment, or of rising into view; sudden uprisal or appearance. The white color of all refracted light, at its very first emergence . . . is compounded of various colors. Sir I. Newton. When from the deep thy bright emergence sprung. H. Brooke.

a lens or mirror, by rays of light from the several points of the object symmetrically refracted or reflected to corresponding points in such focus; this may be received on a screen, a photographic plate, or the retina of the eye, and viewed directly by the eye, or with an eyeglass, as in the telescope and microscope;…

to incline, to deflect; to curve; to bow. Are they [the rays of the sun] not reflected, refracted, and inflected by one and the same principle Sir I. Newton.

Not refrangible; that can not be refracted in passing from one medium to another. -- Ir`re*fran"gi*ble*ness, n.

f refraction or reflection (Opt.), the plane in which lie both the incident ray and the refracted or reflected ray.

ction for the extraordinary ray is greater than for the ordinary ray, and the former is refracted nearer to the axis than the latter, as quartz and ice; -- opposed to negative crystal, or one in which this characteristic is reversed, as Iceland spar, tourmaline, etc. -- Positive degree (Gram.), that state of an adject…

gether so as to have opposite relative positions, a ray of light passed through them is refracted or bent into a new position, but is free from color. -- Nicol's prism, Nicol prism. Etym: [So called from Wm. Nicol, of Edinburgh, who first proposed it.] (Opt.) An instrument for experiments in polarization, consisting o…

Capable of being refracted.

Opt.), the angle of a triangular prism included between the two sides through which the refracted beam passes in the decomposition of light. -- Refracting telescope. (Opt.) See under Telescope.

The act of refracting, or the state of being refracted.

Capable of being refracted, or turned out of a direct course, in passing from one medium to another, as rays of light. -- Re*fran"gi*ble*ness, n.

ion, appear to issue; the point at which converging rays would meet if not reflected or refracted before they reach it. -- Virtual image. (Optics) See under Image. -- Virtual moment (of a force) (Mech.), the product of the intensity of the force multiplied by the virtual velocity of its point of application; -- somet…
