"Refractive" Quotes from Famous Books
 ... forms; (4) The laws of metallic reflection; (5) Experiments on the absorption of light. In this line of investigation the prime importance belongs to the discovery (1) of the connexion between the refractive index and the polarizing angle, (2) of biaxial crystals, and (3) of the production of double refraction by irregular heating. These discoveries were promptly recognized. So early as the year 1807 the degree ...

... by means of light that is itself invisible? Could anything have been more unexpected than to find that a sphere of China-clay focuses invisible light more perfectly than a sphere of glass focuses the visible; that in fact, the refractive power of this clay to electric radiation is at least as great as that of the most costly diamond to light? From amongst the innumerable octaves of light, there is only one octave, with power to excite the human eye. In reality, we stand, in the midst of a luminous ...

... passes out of one medium into another of different density, it is bent out of its course, and is said to be refracted. We must, however, except those rays which fall in a direction perpendicular to the surface of the refracting medium; as the refractive force acts in the same direction in which those rays move, they will not be turned out of their course, but proceed in the same direction they had before they entered the refracting medium. When a ray passes out of a rarer into a denser medium, ...

... laboratory in Blackman Street, by precipitating and working a large quantity of borate of lead, and fusing it under a muffle in a porcelain evaporating dish. A very limpid (though slightly yellow) glass resulted, the refractive index 1.866! (which you will find set down in my table of refractive indices in my article "Light," Encyclopaedia Metropolitana). It was, however, too soft for optical use as an object- glass. This Faraday overcame, at least to a considerable degree, by the ...

... of Nature instead of thwarting them; but then this is His machinery, which He has not explained to us. He presents Himself to us, acting sometimes supernaturally; i.e. in a way above nature as we understand nature. He made the Sun to stand still for Joshua; what refractive cloud came in and held the daylight that it should not go down is not made known to us; GOD said that it should stay, and it stayed; there was the miracle. To have set the Creation going two thousand ...
