Neither when I spoke of red, or blue, and green, as well as refrangibility, had I these several colors, or the rays of light passing into a different medium, and there diverted from their course, painted before me in the way of images.
Newton sets forth his classic experiments showing that light is a heterogeneous mixture of rays of different refrangibility, and that rays of different refrangibility differ also in color.
According to rigid Newtonians, air is transparent, or, rather, invisible; and the azure colour of the atmosphere arises from the greater refrangibility of the blue rays of light.
When the angle of incidence is increased, the band moves in the direction of increasing refrangibility, and at the same time increases rapidly in width.
Undersökningar, _ presented to the Stockholm Academy in 1853, he not only pointed out that the electric spark yields two superposed spectra, one from the metal of the electrode and the other from the gas in which it passes, but deduced from Euler's theory of resonance that an incandescent gas emits luminous rays of the same refrangibility as those which it can absorb.
[Shown.] (2) As the angle of incidence is increased, the reflected light becomes brighter and rises in refrangibility.
The principal experiments also indicate that it is the rays of highest refrangibility -- the blue-violet and ultra-violet rays of the spectrum -- which bring about the destruction of the organisms (figs. 17, 18).
If we hold with Professor Allman that thought, will, and conscience, though only manifesting themselves through the medium of cerebral protoplasm, are not its properties any more than the invisible earth elements which lie beyond the violet are the property of the medium which, by altering their refrangibility, makes them its own -- then the study of the exact nature and properties of the transmitting medium is equally necessary.
The presence or absence of spores; when present, spores show their typical refrangibility exceedingly well by this method.
Doppler's principle, by which light alters in refrangibility through the end-on motion of its source, was first made effective for astronomical reseach by 1868.
