POLA
n.
That which polarizes; especially, the part of a polariscope which receives and polarizes the light. It is usually a reflecting plate, or a plate of some crystal, as tourmaline, or a doubly refracting crystal.
n.
A property of the conic sections by virtue of which a given point determines a corresponding right line and a given right line determines a corresponding point. See Polar, n.
imp. & p. p.
of Polarize
n.
That quality or condition of a body in virtue of which it exhibits opposite, or contrasted, properties or powers, in opposite, or contrasted, parts or directions; or a condition giving rise to a contrast of properties corresponding to a contrast of positions, as, for example, attraction and repulsion in the opposite parts of a magnet, the dissimilar phenomena corresponding to the different sides of a polarized ray of light, etc.
n.
The art or process of measuring the polarization of light.
a.
Pertaining to, reckoned from, or having a common radiating point; as, polar coordinates.
a.
Pertaining to, or exhibiting, poles; having a polar arrangement or disposition; arising from, or dependent upon, the possession of poles or polar characteristics; as, polaristic antagonism.
n.
An instrument for determining the amount of polarization of light, or the proportion of polarized light, in a partially polarized ray.
n.
An instrument consisting essentially of a polarizer and an analyzer, used for polarizing light, and analyzing its properties.
n.
The art or rocess of making observations with the polariscope.
a.
Of or pertaining to one of the poles of the earth, or of a sphere; situated near, or proceeding from, one of the poles; as, polar regions; polar seas; polar winds.
n.
The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line. If the given point lies within the curve so that the two tangents become imaginary, there is still a real polar line which does not meet the curve, but which possesses other properties of the polar. Thus the focus and directrix are pole and polar. There are also poles and polar curves to curves of higher degree than the second, and poles and polar planes to surfaces of the second degree.
a.
Electrically polarized like the surface of the zinc presented to the acid in a battery, which has zincous affinity.
adv.
In a polary manner; with polarity.
n.
The act of polarizing; the state of being polarized, or of having polarity.
v. t.
To communicate polarity to.
a.
Of or pertaining to the polariscope; obtained by the use of a polariscope; as, polariscopic observations.
p. pr. & vb. n.
