( Note: Because of light leakage from one ultraviolet source to another, the lights are switched by a commutator-like assembly rotated by a synchronous motor.

Because CCD imagers are linear, image processing may be used to subtract away the effects of light pollution, which has increased the popularity of astrophotography in urban areas.

Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave.

Because hemoglobin is a darker red when it is not bound to oxygen ( deoxyhemoglobin ), as opposed to the rich red color that it has when bound to oxygen ( oxyhemoglobin ), when seen through the skin it has an increased tendency to reflect blue light back to the eye.

Because of its relative nuclear instability, lithium is less common in the solar system than 25 of the first 32 chemical elements even though the nuclei are very light in atomic weight.

Because of the metallic gold's bright color, the gold jerseys were considered the " light " jersey in the game, so the Vikings wore their purple home jerseys as the " dark " colored team.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Because open clusters tend to be dispersed before most of their stars reach the end of their lives, the light from them tends to be dominated by the young, hot blue stars.

Because of the great distances to the farthest quasars and the finite velocity of light, we see them and their surrounding space as they existed in the very early universe.

Because the light of the flash occurs too fast for the pupil to close, much of the very bright light from the flash passes into the eye through the pupil, reflects off the fundus at the back of the eyeball and out through the pupil.

Because this interaction takes place on atomic electrons it occurs with the same rate in both the heavy and light water.

Because it retains its strength at high temperatures and has a high melting point, elemental tungsten is used in many high-temperature applications, such as light bulb, cathode-ray tube, and vacuum tube filaments, heating elements, and rocket engine nozzles.

Because a tachyon always moves faster than light, we cannot see it approaching.

Because the object arrives before the light, the observer sees nothing until the sphere starts to pass the observer, after which the image-as-seen-by-the-observer splits into two — one of the arriving sphere ( to the right ) and one of the departing sphere ( to the left ).

Because the group velocity for such a field is superluminal, naively it appears that its excitations propagate faster than light.

Because the patterned portion of the page is thinner, it transmits more light through and therefore has a lighter appearance than the surrounding paper.

Because of the techniques used in its creation, short mead shares some qualities found in cider ( or even light ale ): primarily that it is effervescent, and often has a cidery taste.

Because relativity treats space and time as a whole, a relativistic generalization of this equation requires that space and time derivatives must enter symmetrically, as they do in the Maxwell equations that govern the behavior of light — the equations must be differentially of the same order in space and time.

Because they convert electricity into laser light with much higher efficiency, diode lasers also run cooler, which in turn allows them to be operated at much higher frequencies.

Because parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays follow sinusoidal paths down the fiber.

Because the permittivity is anisotropic, polarized light of different orientations will travel at different speeds.

Because the MO activity is usually very small, normally less than 1 °, in conventional systems, the monochromator produces quasi-monochromatic light in a narrow wavelength window since the amplitude of modulation is wavelength dependent.

Because of the longer measures, they are longer than the reel and the light jig, with the same number of bars to the music.

Because Bright's speeches were so much a part of him, there are long and numerous quotations, which, far from making the biography diffuse, help to give us the feel of the man.

Because negative pressure dialysis gave better recovery of proteins, permitted detection of proteins concentrated from very dilute solutions and was a gentler procedure, it was used in all but the earliest experiments.

Because electrical forces ( the charge-excess ) are far more powerful than gravitation, the surface hydrogen atoms would shoot away from the sphere.

Because anthropology developed from so many different enterprises ( see History of Anthropology ), including but not limited to fossil-hunting, exploring, documentary film-making, paleontology, primatology, antiquity dealings and curatorship, philology, etymology, genetics, regional analysis, ethnology, history, philosophy, and religious studies, it is difficult to characterize the entire field in a brief article, although attempts to write histories of the entire field have been made.

Because the levels themselves are random variables, some assumptions and the method of contrasting the treatments ( a multi-variable generalization of simple differences ) differ from the fixed-effects model.

Because of these natural conditions, the Black Sea coast historically has been isolated from Anatolia.

Because not from a man she conceived but from the Holy Spirit.

Because of this, Hasan Ali Shah decided to secure a pledge of loyalty from the members of the community to himself and to the Ismaili form of Islam.

Because the position of Stigand, the archbishop of Canterbury, was irregular, Wulfstan sought and received consecration as a bishop from Ealdred.

Because it occupies a part of the celestial sphere that faces away from the Milky Way, Antlia contains very few deep-sky objects.

Because of its elevation and distance from the coast, the Australian Capital Territory experiences four distinct seasons, unlike many other Australian cities whose climates are moderated by the sea.

Because of your forward motion relative to the falling rain, the rain now appears to be falling not straight down from directly above you, but at a slight angle from a point in the sky somewhat in front of you.

Because of the market success of the NES, companies chose to develop for it first and were thus barred from developing the same games on competing systems for two years.

Because these methods are diverse and use data from such different sources, the problem of integrating them into a coherent argument has been a long-term issue for archaeoastronomers.

Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.

Because of the radical departure from traditional behavior and theatrical convention involved in Nora's leaving home, her act of slamming the door as she leaves has come to represent the play itself.

Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet.

Because the Belarus government severely limits free expression, several opposition media outlets are broadcast from nearby countries to help provide Belarusians alternative points of view.

Because of the split in the Conservative Party and because of Disraeli's unpopularity, arising from the budget fight of 1852, which is outlined above, no Conservative reconciliation remained possible so long as Disraeli remained leader in the House of Commons.

Because F ( x ) is a map from X ′ to K, it is an element of X ′′.

Because of a wine glut ( wine lake ) in the generic production, the price squeeze induced by an increasingly strong international competition, and vine pull schemes, the number of growers has recently dropped from 14, 000 and the area under vine has also decreased significantly.
