Show TDK UNSEKD AND TDK I'NIIKARD The primary colors shown In the rainbow vary from red to blue and viol .-(, and the vibrations, or lengths of the light waves that give iu violet grow shorter and shorter and at length give us red. These vibrations enn be measured. One day, cpilte by chance. I came across the statement that there were Innumrable light waves longer than those which give violet At oneo the question sprang: were these longer waves represent d by colors which we don't see, colors of which we can form no conception? And was the same thing true of the waves which, growinc shorter and shorter, give us the sensation of red' There Ik room, of course, for myralda of colors beyond thU extremity of our vision. A little study convinced ine that my guess was right: for all the colors which we see are represented to our sense of feeling In degres of heat; that is, blue shows one reading on the thermometer and red a h'gher reading: and. by niean-s of th i h new standard. 1 discovered that man's range of vision is not even placed in tlm middle of the register of heat, tint orcnplcn a llttlf ?pace far up toward to-ward tho warmer extremity of It.', There are thousands of decrees of1 cold lower than blue and hundreds of degrees of heat above red. All these graduations are doubtless represented represent-ed by colors which no human eye can perceive, no human m'nd imagine. U Is with sight as with sound. We know now that there are noises louder than thunder which we cannot hear, the roar that lies on the other .hle of -lence. Wo mn are poor, restless prlponers, hemmed In bv our senses as by the walls of a cell hearing ocly a part of nature's orchestra and t'at part Imperfectly e.-ng only a a thousandth part of the color marvels mar-vels about ns and seelnc that Infinitesimal Infinit-esimal part incorrectly and partially Frank Harris In The Forum. |
