Casaubon quite shamefully: I think you would have given up ever coming to see me if he had asked you." "Of course I submitted to him, because it was my duty; it was my feeling for him," said Dorothea, looking through the prism of her tears. "Then why can't you think it your duty to submit a little to what James wishes?" said Celia, with a sense of stringency in her argument.
The ray has or may have a colour of its own before it passes through the prism. The prism spreads it out and shows a series of colours. The order in which this series is arranged is determined by the character of the prism acting on the nature of the ray.
First, she went back to what Uncle Darcy had told her, and imagined herself as rescuing an only child who was drowning. The whole town stood by and cheered when she came up with it, dripping, and the mother took her in her arms and said, "You are our prism, Georgina Huntingdon! But for your noble act our lives would be, indeed, desolate. It is you who have filled them with rainbows."
Each whiff of colorless gas in its test-tube interferes with the light passing through it in such a way that when viewed through a prism it gives a spectrum of altogether unique lines, which stamp it as krypton, neon, or zenon as definitely as certain familiar and more tangible properties stamp the liquid which imprisons it as mercury.
All harmonies start from a common centre and preserve the closest relations among themselves; or rather, harmony, like light, is decomposable by our art as a ray is by a prism." He then displayed the instruments constructed in accordance with his laws, explaining the changes he had introduced into their constitution.

Then far eastward toward Vancouver his glass picked up two formless dots which alternately showed and disappeared.
Newton was led to his discovery by some experiments made with an ordinary glass prism applied to a hole in the shutter of a darkened room, the refracted rays of the sunlight being received upon the opposite wall and forming there the familiar spectrum.
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.
I read your letter to papa, telling all about your birthday and the prism Uncle Darcy gave you. It cheered him up wonderfully. I was so proud of you when he said it was a fine letter, and that he'd have to engage you as a special correspondent on his paper some day.
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.
