The angle of polarization is the angle at which a beam of light must be reflected, in order that the polarization may be the most complete.

Physics) Defn: Turning or twisting the plane of polarization towards the left, as levulose, levotartaric acid, etc.
The term polarizationwas derived from the theory of emission, and it was conceived that each luminous molecule has two poles analogous to the poles of a magnet; but this view is not now held.

It is called levulose, because it rotates the plane ofpolarization to the left.
Defn: An instrument for determining the amount of polarization of light, or the proportion of polarized light, in a partially polarized ray.
The two acids are alike in having the same constitution (expressed by the name ethylidene lactic acid), but the latter is optically inactive, while sarcolactic acid rotates the plane of polarization to the right.
And it is evident that the planes of polarization of the ordinary and extraordinary rays are opposite, from the opposite action of the analyzer upon them.
Thus the colours produced by polarization are the same as those of the spectrum, but separated in a different way, both arising from the elementary coloured rays of the compound white light.
The sugar to be of any grade or grades of Raw sugars based on Cuban Centrifugal of 96 degrees average polarization outturn at the price of .
Blanc has shown, however, that the effect of ammonium amalgam on the magnitude of polarization of a battery is comparable with that of the amalgams of the alkali metals.
Plante began his work on electrolytic polarization in 1859, his object being to investigate the conditions under which its maximum effects can be produced.
The establishment and convection of a single polar atom constitutes in fact a quasi-magnetization, in addition to the polarization current as above defined, the negative poles completing the current circuits of the positive ones.
Interpretation of the Polarization of Light Reflected by the Different Regions of the Surface of Mars.
If inorganic interpretations of the seasonal albedo variation are accepted, then an inorganic interpretation must also be advanced for the polarization variation.
It was of course well known, as a necessity of Maxwell's mathematical theory, that the polarization and depolarization of an insulator must give rise to the same electromagnetic effects in the neighbourhood as a voltaic current in a conductor.
Crystals of most substances of this class rotate the plane of polarization of a beam of light.
The circular polarization of crystals may be imitated by a pile of mica plates, each plate being turned through a small angle on the one below, thus giving a spiral arrangement to the pile.
Like the solutions of certain optically active organic substances, such as sugar and tartaric acid, some optically isotropic and uniaxial crystals possess the property of rotating the plane of polarization of a beam of light.
Spike oil turns the plane of polarization only slightly to the left, the deviation scarcely ever exceeding 0.
It closely resembles the French oil, but turns the plane of polarizationto the left.
Its specific gravity, boiling point and chemical properties are the same as those of the carvol of caraway oil, but it differs from it by its odor and turning the plane of polarization to the opposite direction.
It is optically inactive or turns the plane of polarization slightly to the right.
It contains a terpene which turns the plane of polarization to the right, and has a lemon-like odor.
It turns the plane of polarization strongly to the left; acquires, on standing with sodium, a red coloration, and detonates with iodine.
It consists mostly of a terpene which turns the plane of polarization to the right, and boils at 320° F.
Polarization may be entirely avoided by the use of a silver nitrate solution and silver electrodes or of a cupric salt solution and copper electrodes (Noyes and Blanchard).
Readings are made three or four seconds after each dilution, when the polarization has been fully established.
Grim and Wat examined with interest the banked controls, the polarization apparatus that set up repulsion waves and literally kicked the ship out into space away from the planet against which it had been set.
He set the polarization controls so that the mere pulling of a switch would send the flier careening off into space.

Elementary application of double refraction and the polarization which accompanies it in uniaxial crystals when the face of the crystal is parallel to the axis, and the plane of incidence normal or parallel to this axis.
Definition of polarization in the system of waves.
The means by which polarization of cells is prevented or reduced in practice may be divided into three general classes: First--mechanical means.
If properly made, they recuperate quickly after polarization due to heavy use.
In other words, the polarization gradually gains on the preventive means and so gradually reduces the current by increasing the resistance of the cell and lowering its electromotive force.
Thus it will be seen that while the cell is free from polarization and local action, there is, nevertheless, a deteriorating effect if the cell is allowed to remain long on open circuit.
Until about the middle of the year 1909, it was the universal practice to employ permanent magnets for giving the initial polarization to the magnet cores of telephone receivers.
On the other hand some cells are so constituted that polarization takes place faster than the means intended to prevent it can act.
Since hydrogen is thus diverted from the copper plate, polarization does not ensue.
It is also occasioned by anodic polarization of iron in sulphuric acid.
Its disappearance seemed to substantiate the polarization theory.
In the case of the copper, polarization also sets in, but never attains to equality with the electro-motive force of the primary battery.
