Prism   Listen
noun
Prism  n.  
1.
(Geom.) A solid whose bases or ends are any similar, equal, and parallel plane figures, and whose sides are parallelograms. Note: Prisms of different forms are often named from the figure of their bases; as, a triangular prism, a quadrangular prism, a rhombic prism, etc.
2.
(Opt.) A transparent body, with usually three rectangular plane faces or sides, and two equal and parallel triangular ends or bases; used in experiments on refraction, dispersion, etc.
3.
(Crystallog.) A form the planes of which are parallel to the vertical axis. See Form, n., 13.
Achromatic prism (Opt.), a prism composed usually of two prisms of different transparent substances which have unequal dispersive powers, as two different kinds of glass, especially flint glass and crown glass, the difference of dispersive power being compensated by giving them different refracting angles, so that, when placed together so as to have opposite relative positions, a ray of light passed through them is refracted or bent into a new position, but is free from color.
Nicol's prism, Nicol prism. (Opt.) An instrument for experiments in polarization, consisting of a rhomb of Iceland spar, which has been bisected obliquely at a certain angle, and the two parts again joined with transparent cement, so that the ordinary image produced by double refraction is thrown out of the field by total reflection from the internal cemented surface, and the extraordinary, or polarized, image alone is transmitted.

"Prism" Quotes from Famous Books



... Flickering, unquiet lights, are sometimes pleasing—to children and idiots always so—but in the embellishment of a room they should be scrupulously avoided. In truth, even strong steady lights are inadmissible. The huge and unmeaning glass chandeliers, prism-cut, gas-lighted, and without shade, which dangle in our most fashionable drawing-rooms, may be cited as the quintessence of all that is false in taste or preposterous ...

... laugh startled Debby, though it was smothered like the babes in the Tower; and, turning, she beheld the trespasser scarlet with confusion, and sobered with a tardy sense of his transgression. Debby was not a starched young lady of the "prune and prism" school, but a frank, free-hearted little body, quick to read the sincerity of others, and to take looks and words at their real value. Dickens was her idol; and for his sake she could have forgiven a ...

... gay fifteen—[49] Yet genius still breaks through the encumbering phrase; His taste we censure, but the work we praise: There learning beams with fancy's brilliant dyes, Vivid as lights that gild the northern skies; Man's complex heart he bares to open day, Clear as the prism unfolds the blended ray: The picture from his mind assumes its hue; The shades too dark, but the design still true. Though Johnson's merits thus I freely scan, And paint the foibles of this wond'rous man; Yet can I coolly read, and not admire, When Learning, Wit and Poetry ...

... hand of Seraphitus, hoping thus to draw him to her, and to lay on that seductive brow a kiss given more from admiration than from love; but a glance at the young man's eyes, which pierced her as a ray of sunlight penetrates a prism, paralyzed the young girl. She felt, but without comprehending, a gulf between them; then she turned away her head and wept. Suddenly a strong hand seized her by the waist, and a soft voice said to her: "Come!" She obeyed, resting her head, suddenly revived, upon the heart of her companion, ...

... case of a colored glass, a prism, or a refracting lens, we have transmissive function. The energy of the light, no matter how produced, is by the glass sifted and limited in color, and by the lens or prism determined to a certain path and shape. Similarly, the keys of an organ have only a transmissive function. ...

... nourished during the bitterness of the struggle. The moment had arrived when practical advantage might be taken from the defeat of the enemy, and it seemed madness to surrender such advantage for the sake of quixotic ideals. The statesmen of Europe once more viewed affairs through the colored prism of national selfishness. In America, where Wilsonian ideals had at best been imperfectly appreciated, men were wearied by international problems and longed for a return to the simple complexity of the business life which they understood. The President was confronted ...

... of God. The tendency of the modern pulpit is to strain out the divine justice from the divine benevolence, to sink benevolence into a sentiment rather than exalt it into a principle. The new theological prism puts asunder what God has joined together. Is the divine law a good or an evil? It is a good. Then justice is good; for it is a disposition to execute the law. From the habit of underrating the divine law and justice, the extent and demerit of human ...

... nature of light. It had been long believed that every colored ray is equally refracted when passing through a lens. Newton determined to analyze the prismatic hues. He made a hole in a window-shutter, and darkening the room, let in a portion of light, which he passed through a prism. The white sunbeam formed a circular image on the opposite wall, but the prismatic colors formed an image five times as long as it was broad. He was curious to know how this came to pass. Satisfied that the length ...

Are not these as plain proofs, that the passions of fear and hope are mixtures of grief and joy, as in optics it is a proof, that a coloured ray of the sun passing through a prism, is a composition of two others, when, as you diminish or encrease the quantity of either, you find it prevail proportionably more or less in the composition?

On the principle that a strawberry is quicker to spoil than a pumpkin, it takes less to render a woman obnoxious than to make a man unfit for decent company. I am no lover of butter-mouthed girls, of prudes and "prunes and prism" fine ladies; I love sprightliness and gay spirits and unconventionality, but the moment a woman steps over the border land that separates delicacy of feeling, womanliness and lovableness, from rudeness, loud-voiced slang and the unblushing desire ...

... the room, and letting just one ray of light stream in through a small hole. Then take a bit of glass, cut so that it has at least three sides—a "drop" of cut glass from the lustre on the mantelpiece will do—and hold it up between you and the light. This little piece of glass, which is called a prism, because it has been sawn or cut, will do a wonderful thing, as you turn it about in the sunbeam. The ray of light, as it passes through the three-cornered bit of glass, will be turned out of its straight path, and this causes it to be split up into many colours, so that you will have ...

I now placed the drop on a thin slip of glass Under the lens, and throwing upon it, by the combined aid of a prism and a mirror, a powerful stream of light, I approached my eye to the minute hole drilled through the axis of the lens. For an instant I saw nothing save what seemed to be an illuminated chaos, a vast, luminous abyss. A pure white ...

He studied the influence of thickness of air-space on total reflection of Electric Radiation and showed that the critical thickness of air-space is determined by the refracting power of the prism and by the wave-length of the electric oscillations. He next demonstrated the rotation of the plane of polarisation of Electric Waves by means of pieces of twisted jute rope. He showed that, if the pieces are arranged so that their twists are all in one direction ...

After passing through a pyramidal room, with triangular sides that sloped to a point, she came to one in the shape of a polygonal prism. In a long, broad corridor she had to walk on a narrow path, bordered by sphinxes; and there she clung tightly to her guide, for on one side of the foot-way yawned a gulf of great depth. In another place she heard, above her head, the ...

But even if the feelings of affection and gratitude that he inspired in me did come like a prism and interpose themselves between my eyes and his face, I do not see anything greatly to be regretted in it.[134] I had not yet felt the charm of his personal fascination, I had neither heard nor seen him, ...

Grasping one of them in his hand, he wrenched it from the branch; but as he did so, the husk dropped off, and the prism-shaped nuts fell like a shower of huge hailstones on the roof of the toldo. "Monkey-pots they're called," continued he, referring to the empty pericarp still in his hand. "That's the name by which the Indians know them; because the monkeys are ...

It depends on the curious property, possessed by nearly all bodies, of absorbing certain parts of the light that passes through them. Sunlight passing through a prism is split up into the familiar seven colours of the rainbow. But if a little blood dissolved in water is placed in a glass tube, and if the light is made to pass through it on its way to the prism, the blood takes something out of it; for now among the seven bright colours are seen two ...

That was all very well as a spectacular exhibition; but how when he was apparently instructing them in some serious matter? Was it fair to ...

... important single step ever taken towards a knowledge of the physics of light, and incidentally towards a knowledge of visual sensations, was Newton's analysis of white light into the spectrum. He found that when white light is passed through a prism, it is broken up into all the colors of the rainbow or spectrum. Sunlight consists of a {213} mixture of waves of various lengths. At one end of the spectrum are the long waves (wave-length 760 millionths of a millimeter), at the other ...

... Schwartz, and assisted by the engineers Kober and Kubler, conceived the idea of constructing a rigid airship of considerable dimensions. For this purpose a floating shed was built on Lake Constance, near to Friedrichshafen. The hull was built of aluminium lattice-work girders, and had the form of a prism of twenty-four surfaces with arch-shaped ends. In length it was 420 feet, with a diameter of 38 feet 6 inches, and its capacity was 400,000 cubic feet. The longitudinal framework was divided by a series of ...

Instead of which, he looked at a part of his pictures through a prism, and at another part through a camera obscura. If the historian were as profuse of moral as of political axioms, we should tolerate him less: for in the political we fancy a writer is but meditating; in the moral we regard him as declaiming. In history we desire to be conversant ...

Upon the sharp edge of this I was made to stand, and several men held me by the body while four or five others, using their combined strength, stretched my legs as wide apart as they could go. Fixed in this painful position, the brutes ...
