Refract
[Noun]
Webster's Dictionary 1913
1. To bend sharply and
abruptly back; to break off.
2. To break the natural course of, as rays of light orr heat, when passing from one transparent medium to another of different density; to cause to
deviate from a direct course by an action distinct from
reflection; as, a dense medium refrcts the rays of light as they pass into it from a rare medium.
Refracted
[Adjective]
Webster's Dictionary 1828
In botany, bent back at an acute angle; as a refracted
corol.
Refracted

Refracted
[Adjective]
Webster's Dictionary 1913
1. Bent backward angularly, as if half-broken; as, a refracted stem or leaf.
2. Turned from a direct course by refraction; as, refracted rays of light.

Refracting
[Participle present tense]
Webster's Dictionary 1828
Turning from a direct course.
Serving or tending to
refract; as, a refracting medium.
1. The
deviation of a moving body, chiefly rays of light, from a direct course. This is occasioned by the different densities of the mediums through which light passes.
2. Refraction out of a rarer medium into a denser, is made towards the perpendicular.
3. Refraction may be caused by a body's falling obliquely out of one medium into another.
4. Refraction double, the separation of a ray of light into two separate parts, by passing through certain transparent mediums, as the Iceland crystal. All crystals, except those whose primitive form is either a
cube or a regular
octahedron, exhibit double refraction
2. 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.
3. The change in the direction of a ray of light, and, consequently, in the apparent position of a heavenly body from which it emanates, arising from its passage through the earth's atmosphere; -- hence distinguished as atmospheric refraction, or astronomical refraction.
4. 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.
REFRACTION. See Light and Optics.

[5 words — estimated reading time: 1 minute]
That refracts or has power to
refract or turn from a direct course; as refractive densities.
Serving or having power to
refract, or turn from a direct course; pertaining to refraction; as, refractive surfaces; refractive powers.
A
contrivance for exhibiting and measuring the refraction of light.
1. Anything that refracts
2. A
refracting telescope, in which the image to be viewed is formed by the refraction of light in passing through a convex lens.
2. I never allowed any man's refractoriness against the privileges and orders of the house.
4. Applied to metals, difficult of fusion; not easily yielding to the force of heat.
1. A person
obstinate in opposition or disobedience.
2. Resisting ordinary treatment; difficult of fusion, reduction, or the like; -- said especially of metals and the like, which do not readily yield to heat, or to the hammer; as, a refractory ore.
1. A refractory person.
3. OPottery) A piece of ware covered with a
vaporable flux and placed in a
kiln, to communicate a
glaze to the other articles.
A second breaking (as of a badly set bone) by the
surgeon.
Refracture
[Verb transitive]
Webster's Dictionary 1913
To break again, as a bone.
