Thanks for using this online dictionary, we have been helping millions of people improve their use of the english language with its free online services. English definition of polar is as below...
Polar (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 th
Lern More About Polar
Polarization ::
Polarization (n.) The act of polarizing; the state of being polarized, or of having polarity..
Levulose ::
Levulose (n.) A sirupy variety of sugar, rarely obtained crystallized, occurring widely in honey, ripe fruits, etc., and hence called also fruit sugar. It is called levulose, because it rotates the plane of polarization to the left..
Depolarization ::
Depolarization (n.) The act of depriving of polarity, or the result of such action; reduction to an unpolarized condition..
Multipolar ::
Multipolar (a.) Having many poles; -- applied especially to those ganglionic nerve cells which have several radiating processes.
Apolar ::
Apolar (a.) Having no radiating processes; -- applied particularly to certain nerve cells.
Dextrose ::
Dextrose (n.) A sirupy, or white crystalline, variety of sugar, C6H12O6 (so called from turning the plane of polarization to the right), occurring in many ripe fruits. Dextrose and levulose are obtained by the inversion of cane sugar or sucrose, and hence called invert sugar. Dextrose is chiefly obtained by the action of heat and acids on starch, and hence called also starch sugar. It is also formed from starchy food by the action of the amylolytic ferments of saliva and pancreatic juice..
Solenoid ::
Solenoid (n.) An electrodynamic spiral having the conjuctive wire turned back along its axis, so as to neutralize that component of the effect of the current which is due to the length of the spiral, and reduce the whole effect to that of a series of equal and parallel circular currents. When traversed by a current the solenoid exhibits polarity and attraction or repulsion, like a magnet..
Inherent ::
Inherent (a.) Permanently existing in something; inseparably attached or connected; naturally pertaining to; innate; inalienable; as, polarity is an inherent quality of the magnet; the inherent right of men to life, liberty, and protection..
Iceland Spar ::
Iceland spar () A transparent variety of calcite, the best of which is obtained in Iceland. It is used for the prisms of the polariscope, because of its strong double refraction. Cf. Calcite..
Idiophanous ::
Idiophanous (a.) Exhibiting interference figures without the aid of a polariscope, as certain crystals..
Isochromatic ::
Isochromatic (a.) Having the same color; connecting parts having the same color, as lines drawn through certain points in experiments on the chromatic effects of polarized light in crystals..
Analyzer ::
Analyzer (n.) The part of a polariscope which receives the light after polarization, and exhibits its properties..
Inactive ::
Inactive (a.) Not active; inert; esp., not exhibiting any action or activity on polarized light; optically neutral; -- said of isomeric forms of certain substances, in distinction from other forms which are optically active; as, racemic acid is an inactive tartaric acid..
Levogyrate ::
Levogyrate (a.) Turning or twisting the plane of polarization towards the left, as levulose, levotartaric acid, etc..
