So as to the business of Refraction, spirit of Wine is a more dense body then Water, it having been found by an accurate Instrument that measures the angles of Refractions to Minutes that for the same refracted angle of 30°.
The eye-piece in question was invented by Huyghens for telescopes, with no other view than that of diminishing the spherical aberration by producing the refractions at two glasses instead of one, and of increasing the field of view.
In this combination the errors are still further reduced by the close approximation to the object which causes the refractions to take place near the axis.
It is formed by two refractions and two reflections, is much fainter than the primary bow, and has its colors arranged in the reverse order from those of the latter.
The authenticity of these manuscripts has been contested: the Almagest contains no mention of the Optics, nor is the subject of astronomical refractions noticed, but the strongest objection, according to A.
But, after I know not what space of time in which I had become half hypnotised by those two tiny refractions of coloured light, I suddenly put the glasses away from me.

Vieyra, "that the play of the terrestrial refractions may render visible to the inhabitants of the Canaries the islands of Cape Verd, and even the Apalachian mountains of America.
PRIME~} from their Perpendiculars; that so the Refractions at the Ingress and Egress may be equal, and the Computations easy.
Is a Figure for the Explication of the several Refractions and Reflections of Light, which cause the Phaenomena of the Rainbow.
It is a fundamental principle, that all superfluousrefractions and reflections are to be avoided in the construction of optical instruments.
These are, again, the refractions of eternal truths, viewed by man from his material plane.
Nature is ever one in her original truths and their duplicate reflections; but ever conflicting and contradictory in her multiplied refractions through the minds of men.
From a careful discussion of the results of observation Mr Stone had concluded that the refractions ought to be diminished.
Relying on this, we have now computed our mean refractions by diminishing those of Bessel's Fundamenta in the proportion of 1 to 0.
The effects of which refractions are very remarkable; for by them we often see objects which the rotundity of the Earth ought otherwise to hide; such as Islands, and the tops of mountains when one is at sea.
Furthermore these refractions are not altogether constant in all weathers, particularly at small elevations of 2 or 3 degrees; which results from the different quantity of aqueous vapours rising above the Earth.
I pass now to the consideration of other sections of the crystal, and of the refractions there produced, on which, as will be seen, some other very remarkable phenomena depend.
So that there are an infinitude of planes which ought to produce precisely the same refractions as the natural surfaces of the crystal, or as the section parallel to any one of those surfaces which are made by cleavage.
The way of measuring the two Refractions of Iceland Crystal.
The refractions of the ray, both on entering and on quitting the prism, are in the same direction, (Fig.
But there was another window in his soul through which he saw life with no refractions whatever; remorselessly, logically.
On which assumption, it is plain that every attempt I had hitherto made to measure refractions by the image, and its elevation, must fall to the ground.
This method is refuted by experiment; it gives the refractions near the perpendicular AC too great in respect of those near the horizon.
Atomic refractions may be obtained either directly, by investigating the various elements, or indirectly, by considering differences in the molecular refractions of related compounds.
Hydroxylic oxygen is obtained by subtracting the molecular refractions of acetic acid and acetaldehyde.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "refractions" in a variety of sentences. We hope that you will now be able to make sentences using this word.
