Book excerpt: Excerpt from The Pathological Effects of Radiant Energy on the Eye: An Experimental Investigation All radiant energy is at present believed to consist of transverse vibrations in the hypothetical ether, all propagated at the same rate and differing only in amplitude and wave length, hence in frequency, which is the reciprocal of wave length. The uniform propagation rate in vacuo is very nearly km. Per second and the wave lengths so far as ordinarily dealt with range from about 01 to about 0002 mm. For ordinary purposes no attention need be paid to the extremely long wave lengths ranging to 1 mm., to the extremely short ones between 0001 and 0002 mm., or to the enormously shorter one still of the order of magnitude of 0000001 111m. Such as the X-rays are believed to be. For the very long waves are not present in material amount in the radiation from ordinary sources. The very short ones are absorbed by a few cm. Or dm. Of air, and the X-rays are practically only produced in apparatus intended for that purpose. The spectra given by all ordinary sources range between the more modest limits just given. In the earlier literature this spectral range used to be divided into heat rays, light rays, and actinic rays, a distinction wholly artificial since the three effects implied are far from being sharply defined. More generally the whole range is divided into the infra red portion, not ordinarily visible and extending from the longest waves to those of about 760 1111, the visible spectrum, extending from about 7601111 to about 395 and the ultra violet portion reaching from 395 up to' the neighborhood of 200 ma. This distinction is not rigorous or with sharp limits. While artificial distinctions have led to many misunderstandings,1_ all radiation of Whatever wave length is convertible into heat wheri absorbed by material bodies and may produce chemical changes as well. As a matter of fact these latter show a general tendency to increase with the frequency of the oscilla tions, so that chemical changes are rare in the infra red and increasingly frequent as one approaches the extreme ultra violet. It is this tend ency that is shown in the pathological changes which may be caused in living cells by the incidence of radiation.
