He thus found, as he had expected to find, that the second prism was more efficacious in bending the violet rays than in bending the red rays. Thus he confirmed the fact that the various hues of the rainbow were each bent by a prism to a different extent, violet being acted upon the most, and red the least.英文原著 · 《Great Astronomers》
What is it that makes common salt crystallize in the form of cubes, and saltpetre in the shape of six-sided prisms? We see no reason why it should not have been just the other way, salt in prisms and saltpetre in cubes, or why either should take an exact geometrical outline, any more than coagulating albumen.英文原著 · 《Medical Essays》
The electric light was brilliantly white, and in various places pink, red and light-blue screens mellowed it into an artistic effect that was very soothing to the eye. The ceiling was hung with festoons of prisms as brilliant as the purest diamonds, and in them, owing to the gently undulatory movement of the vessel, colors more beautiful than those of a rainbow played entrancingly. Rare pictures in frames of delicate gold were interspersed among the clusters of prisms, and the floor was covered with carpets that felt as soft beneath the foot as pillows of eider-down.英文原著 · 《The Land of the Changing Sun》
This can be understood when I say, that white light is a bundle of colored rays united together, and when so incorporated, they are colorless; but in passing through the prism the bond of union is severed, and the colored rays come out singly and separately, because each ray has a certain amount of refracting (bending) power, peculiar to itself. These rays always hold the same relation to each other, as may be seen by comparing every spectrum or rainbow; there is never any confusion or misplacement.英文原著 · 《American Hand Book of the Daguerreotype》
white light besides the prism, of which one of the principal and most interesting to the Daguerreotypist is by reflection from colored bodies. If a beam of white light falls upon a white surface, it is reflected without change; but if it falls upon a red surface, only the red ray is reflected: so also with yellow and other colors. The ray which is reflected corresponds with the color of the object. It is this reflected decomposed light which prevents the beautifully-colored image we see upon the ground glass in our cameras.英文原著 · 《American Hand Book of the Daguerreotype》
Artificial lights differ in their color; the white light of burning charcoal, which is the principal light from candles, oil and gas, contains three rays--red, yellow, and blue. The dazzling light emitted from lime intensely heated, known as the Drummond light, gives the colors of the prism almost as bright as the solar spectrum.英文原著 · 《American Hand Book of the Daguerreotype》
