The third is the different refrangibility of the light; for the most refrangible rays do not collect in the same place with the lesser.
On looking into the glass or fluid there will be seen, commencing amidst the most refrangible rays, a new set of spectral rays, struggling to make their way through the absorbent medium.
These are of a blue colour in the quinine or chesnut solution, and green in the uranium glass, and are seen extending themselves far beyond the most refrangible rays of the ordinary Newtonian spectrum.
Wollaston has shown, rays more refrangible than the blue, which produce the same chemical effect, and, what is very remarkable, are invisible.
Which is Blue without, by the more refrangible Rays at H; and Red within by the least at G.
It may be added also that, as Quantz has found, we overestimate the magnitude of colors of the less refrangiblepart of the spectrum and underestimate the others.
In this connection I am led to speak of the common idea that electric light is injurious to the eyes, first, because of its unsteady character, and secondly, by reason of the great excess of the more refrangible rays.
No doubt this is so with light containing the highly refrangible rays in excess; but it is difficult to see how such an effect can occur with light composed as is the light with which the eyes are constructed to operate in perfect harmony.
In passing from the most refrangible ultra-violet to the less refrangible red rays, the responsive retardation of growth undergoes a diminution and practical abolition.
The less refrangible yellow and red rays are practically ineffective.
Ultra-violet light exerts the most intense reaction which reaches a minimum towards the less refrangible red end of the spectrum.
Different observers have found[V] that it is the more refrangible rays which exercise the greatest influence upon growth and tropic curvature.
Luminous radiation of the morerefrangible portion of the spectrum; ultra-violet rays; thermal radiation in the infra-red region.
In addition, it appears to involve a difference in the action of the muscles of accommodation in the successive adaptations of the eye to the most refrangible and the least refrangible rays.
The greater part of the rays of heat are even lessrefrangible than the least refrangible rays of light, while the chemical rays are more refrangible than either.
According to the Newtonian theory the yellow-red (red) is the least refrangible colour, the violet the most refrangible.
At the lessrefrangible end of the solar spectrum, then, the range of the sun's radiation is not limited by that of the eye.
The same statement applies to the more refrangible end.
Hence, in this case, the more refrangible rays are the most chemically active.
Light is decomposed by the prism, because its component parts are refrangible in different degrees, by the same refracting medium.
More slowly, an insulated solar image is whitened in the less refrangible portion of the red.
The maximum of intensity is found at the edge of the most refrangible violet rays, or a little beyond it, varying slightly according to the kind of paper used, and the quantity of free nitrate of silver present.
A yellow solution of picric acid also allows the green to pass, but quenches all the more refrangible light.
Cutting off the more refrangible fringe by a card, the rectangle is seen red: cutting off the lessrefrangible fringe, the rectangle is seen blue.
This blue liquid is blue because it destroys all the less refrangible rays.
You have already seen that the fine blue ammonia-sulphate of copper transmits a large portion of green, while cutting off all the less refrangible light.
We have, firstly, in solar light an agent of exceeding complexity, composed of innumerable constituents, refrangible in different degrees.
In general terms, the more refrangible the light the smaller were the rings.
This red glass is red because it destroys all the more refrangible rays of the spectrum.
In the prismatic spectrum the less refrangible rays are compressed into a much smaller space than in the diffraction spectrum.
And the more refrangible the light the greater is the amount of twisting; so that, when white light is employed, its constituent colours are thus drawn asunder.
Angles of Refraction of the most and least refrangible Rays 54 deg.
But that the meaning of this Experiment may more clearly appear, it is to be considered that the Rays which are equally refrangible do fall upon a Circle answering to the Sun's Disque.
And the contrary happens in the posture of the Paper [Greek: de], the more refrangible Rays being then predominant which always tinge Light with blues and violets.
Then I inclined it the contrary Way, that the least refrangible Rays might be more copious in the reflected Light than the rest, and the Whiteness turned successively to yellow, orange, and red.
Because red rays are the least refrangible of all; and, therefore, are the last to disappear.
Because red rays are the least refrangibleof all, and not being bent back by the air (like blue and green), strike upon the horizon, and give a tinge to the morning clouds.
Hence lightning is red when seen through a dark cloud, or near the horizon; because the more refrangible rays cannot permeate so dense a medium.
Mr. Melville observes, that the blue rays being more refrangible are bent down in the evenings by our atmosphere, while the red and orange being less refrangible continue to pass on and tinge the morning and evening clouds with their colours.
This is necessary, because the focus of the least refrangible or red rays is longer than that of the more refrangible or blue rays.
It was a shrewd guess of Sir Isaac Newton that the diamond is combustible; he did not suspect it to be carbon, but he knew it to be highly refrangible as are many combustible bodies.
The light of the sun consists of rays differently refrangible and reflexible.
Physics) Defn: Lying outside the visible spectrum at its violet end; -- said of rays more refrangiblethan the extreme violet rays of the spectrum.
Physics) Defn: Lying outside the visible spectrum at its red end; -- said of rays less refrangible than the extreme red rays.
Physics) Defn: Situated beyond or below the red rays; as, the ultrated rays of the spectrum, which are less refrangible than the red.
The fundamental green ray had, on the West African plates, seven more refrangible associates;[573] but all alike are of unknown origin.
Footnote 544: The sensitiveness of chloride of silver extends from h to H; that is, over the upper or more refrangible half of the space in which the main part of the coronal light is concentrated.
On the other hand, when a complete spectrum was caused to revolve upon the screen, the whole of its recurrent image from end to end appeared violet; there was no suspicion of blue or greenish-blue at the less refrangible end.
The diffusion circles produced by the red rays, when the eye is accommodated (as it commonly is) for the yellow and green, are less conspicuous than those due to the most refrangible rays.
Every point is expanded into a luminous circle, which is the larger the more refrangible the rays, and it is the extension of these diffusion circles beyond the proper boundaries of the image that gives the appearance of increased breadth.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "refrangible" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: diffuse; dispersed; distorted; scattered; skew; skewed
