Function of a prism

Usage examples of refraction.

He was sufficiently impressed that Murrell had been able to pick out the slender tree across the glade, let alone snap-shoot through the flickering firelight, the smoke and heat-wave refraction, and hit it with even one of his bullets.

What had looked to be vague glints, odd refractions of the sunset, he now realized were photic reactions of some sort.

Freshly fallen from high, stratospheric clouds, the delicate frost coated every surface, from spars and rails to rigging, making the Manitou into a fairy ship of crystal dust, glowing in a profusion of pink sunrise refractions.

The country over which French was operating is dotted with those singular kopjes which the Boer loves--kopjes which are often so grotesque in shape that one feels as if they must be due to some error of refraction when one looks at them.

Every object attitudinizes, to the very mountains and stars almost, under the refractions of this wonderful humorist, and instead of the common earth and sky, we have a Martin's Creation or Judgment Day.

When the Sector arrives, they set up upon a Bluff overlooking Monon-gahela, and watch the Culmination of Stars in Lyra and Cygnus, correcting for seconds plus and minus of Aberration, Deviation, Precession, and Refraction, whilst in Cabins nearby the Wives of the new-hir'd Axmen gather, and those Axmen who may, come thro', and out the back, to take White Maize Whiskey out of a Tin Cup.

Polarizing microscopes show birefringence-the double refraction of crystals and fibers and some other materials.

Traffic on the opposite carriageway had also been stopped by the police, the flashing blue lights slowing to red as they shone through the fringes of the black mass, distorting the image of the road beyond like the refraction on the edge of a jam jar.

There was a file on Snell's Law, which states that a ray of light passing from one uniform medium to another produces an identical ratio between the sine of the angle of incidence and the sine of the angle of refraction, which Klaus already knew.

It was fitted and filled with looking-glasses at every angle of refraction, so that they looked like the hundred facets of one huge diamond--if one could get inside a diamond.

Certainly the angles of refraction are constant, I've measured those already.

In 1875, for instance, a Scottish physicist, John Kerr (1824-1907), had shown that glass and other substances could be made to exhibit double refraction in an intense electric field.

Blondlot set up a very ingenious and delicate experimental procedure that would measure the time it took for the double refraction to appear after the intense electric field had come into being.

Eventually Iwang worked up a law of refraction which he assured Khalid would account for all the colours.

To Molly, this seemed not to be the usual eye-shine of animals in the dark, but a phenomenon unique to this night, not simple light refraction, not bioluminescence, but something of a wondrous character: nimbuses pooled in sockets, signifying sanctification.
