It is well known, that physicists are enabled at present to distinguish two kinds of light--natural light and polarised light.
A polarisedray is said to have sides, and the different sides have different properties, as demonstrated by many interesting phenomena.
With this instrument, it becomes possible to tell the difference between natural and polarised light.

He showed that these polarised the electric rays just as they did ordinary light.
The fruitful theory of stereochemistry was strengthened by the production of two kinds of artificial molecules, which like the two kinds of sugar, rotated the polarised electric wave either to the right or to the left.
But, as the light continued to act, the cloud became coarser and whiter, particularly at its centre, where it at length ceased to discharge polarised light in the direction of the perpendicular, while it continued to do so at both ends.
Sending the polarised beam through the tube, I placed myself in front of it, my eye being on a level with its axis, my assistant occupying a similar position behind the tube.
The light is scattered and polarised by particles, not by molecules or atoms.
From the track of the beam polarised light was discharged; but the direction of maximum polarisation, instead of being perpendicular, now enclosed an angle of only 12° or 13° with the axis of the beam.
Instead of cutting our grain of corn into slices and subjecting it to the action of polarised light, let us place it in the earth, and subject it to a certain degree of warmth.
When this is examined by polarised light, chromatic phenomena similar to those noticed in crystals are observed.
Hence this beam, like the sky, exhibited a neutral point, on opposite sides of which the light was polarised in planes at right angles to each other.
Thin plates of selenite or of quartz, placed between the Nicol and the actinic cloud, displayed the colours of polarised light, these colours being most vivid when the line of vision was at right angles to the experimental tube.
Suffice it to state here that he showed that in the case of aray of plane-polarised light the effect of the magnetic force is to turn the plane of polarisation round the direction of the ray as an axis, through a certain angle.
In optical language, the wave sent out by the aerial would be called a plane polarised wave, the plane of polarisation being parallel to the magnetic force.
The relay that is generally used is a modified form of the Siemens polarised relay, which is so adjusted as to make a single contact.
The light is polarised in planes passing through the {410} eye of the observer, and arcs of great circles intersecting the sun's disc.
Jensen's plan directly polarised by being in actual magnetic contact by the connection of the gimbal (which is one piece with the armature) with the core iron of their magnet.
Indicators of this class, owing to the fact that their replacement depends on the polarity of the bar magnet, are also known as "polarised indicators.
They are both mobile, colourless liquids, having the well-known odour of turpentine and highly refractive; but the French terebenthene turns a ray of polarised light to the left -40.
This action on polarised light is retained in the various compounds and polymers of the two turpentine oils.
There are two cocaines--the one rotating a ray of polarised light to the left, the other to the right.
It possesses scarcely any alkaline reaction, but its salts have an acid reaction; it has but little effect on a ray of polarised light.
If this is so, we seem left to conclude that, in spite of its unequal and polarised attractions, there is equal retardation and equal ionisation in the molecule in whatever 234 direction it is approached.
It is well known that there is in biotite a maximum absorption of a plane-polarised light ray, when the plane of vibration coincides with the plane of cleavage.
The halo extends across both crystals, but owing to the fact that polarised light is used in taking the photograph it appears darker in one crystal than in the other.
Owing to the opposition of its two classes of crystals, a solution of this salt, it will be remembered, does not turn the plane of polarised light either to the right or to the left.
But while the dissolved tartrate causes the plane of polarised light to rotate, the paratartrate exerts no such action.
They constituted the outward and visible sign of that inward and invisible molecular structure which produced the observed action, and difference of action, on polarised light.
Dessaignes were true, then bodies which were inert in regard to polarised light, and consequently non-dissymmetric, could be transformed in the laboratory into active dissymmetric bodies.
In the state of solution they did not turn the plane of polarised light.
The substances which acted upon polarised light, as liquids or solutions, were generally found by Pasteur to produce dissymmetric crystals.
None of these products exert an action on polarised light or show any dissymmetry in the form of their crystals.
Supposing a plate of glass is presented at the angle 56° to a polarised ray, and the plane of incidence or reflexion is at right angles to the plane of polarisation of the ray, no light is reflected.
Precisely the same result takes place when, instead of being reflected, the polarised ray is transmitted.
A polarised ray of light is not transmitted in all the positions of the permeable medium.
It is somewhat difficult to explain what is meant by, and what are the conditions of, polarised light.
If, however, we look at a pencil of polarised light, and turn the crystal round, it will be found that in two positions the light is stopped, and that in two other positions it passes freely through it to the eye.
A polarised ray of light is not reflected in all positions of the reflecting surface.
This was found to be true by Kirchoff himself, who detected and roughly measured the polarised light emitted.
And here may be mentioned also Thomson's explanation of the phenomenon, discovered by Faraday, of the rotation of the plane of a beam of polarised light which is passed along the lines of force of a magnetic field.
This rotation is distinct altogether from that which is produced when polarised light is passed along a tube filled with a solution of sugar or tartaric acid.
N, the windings of which are connected with the battery B and the polarised relay K.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "polarised" in a variety of sentences. We hope that you will now be able to make sentences using this word.
