Exempel på hur man kan använda PRISM i en mening

• Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
• The word spectrum was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.
• A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured.
• The beam divergence at an emitting surface, such as that of a light-emitting diode (LED), laser, lens, prism, or optical fiber end face.
• Danjon devised a method to measure "earthshine" on the darkside of the Moon using a telescope in which a prism split the Moon's image into two identical side-by-side images.
• Erosion at Shishmaref is unique along the islands because of its fetch exposure and high tidal prism, relatively intense infrastructure development during the 20th century, and multiple shoreline defense structures built beginning in the 1970s.
• Reyes, however, disputes this etymological origin, as the name Soloi appears on the Esarhaddon prism predating Solon's visit.
• In optics, one important and familiar consequence of dispersion is the change in the angle of refraction of different colors of light, as seen in the spectrum produced by a dispersive prism and in chromatic aberration of lenses.
• The original "Radiation Analyzer" consisted of a chamber to hold a sample of material, a glass prism to refract the "eloptic" emanations coming from it, and a copper wire probe on a rotating armature to adjust the angle formed by the prism and the probe.
• Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).
• A monocular is a compact refracting telescope used to magnify images of distant objects, typically using an optical prism to ensure an erect image, instead of using relay lenses like most telescopic sights.
• In many cases the time domain is not specifically employed in practice, such as when a dispersive prism is used to obtain a spectrum of light in a spectrograph, or when a sound is perceived through its effect on the auditory receptors of the inner ear, each of which is sensitive to a particular frequency.
• In 1885, Edward Pickering began to supervise photographic spectroscopy at Harvard College Observatory, using the objective prism method.
• A pentaprism is a five-sided reflecting prism used to deviate a beam of light by a constant 90°, even if the entry beam is not at 90° to the prism.
• Monochromatic green light from a mercury source Hg passed through a Nicol polarizing prism N before entering the vacuum chamber, and was split by a beam splitter B set at Brewster's angle to prevent unwanted rear surface reflections.
• Soon after this, he combined telescope and prism to observe the spectrum of Venus, the Moon, Mars, and various stars such as Betelgeuse; his company continued to manufacture and sell high-quality refracting telescopes based on his original designs until its closure in 1884.
• Dispersive prisms are used to break up light into its constituent spectral colors because the refractive index depends on wavelength; the white light entering the prism is a mixture of different wavelengths, each of which gets bent slightly differently.
• Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces.
