Sensitiveness of the Eye to the Spectrum with Moderate Illumination. (Base Line = Wave lengths X 2S°iOoo times). As shown in this curve the normal human eye with moderate illumination has its maximum sensitiveness at about wave length , that is, in the green next the yellow. With very briUiant light the greatest sensitiveness is in the yellow, while with dim light it moves along well into the green. (See § 406 for designation of wave lengths in microns, etc.). Ultra-violet Short radiation invisible to the eye. Compare the sensitive- ness of the photographic plate to this radiation (fig. 140-142). Violet-blue Radiation at the blue end of the spectrum. Green Radiation in the middle of the spectrum. Red Radiation at the red end of the spectrum. Infra-red Long radiation invisible to the eye. G Y Borderland between green and yellow. B G Borderland between blue and green. (2) But as all of these color-sensitive plates are more sensitive to the violet-blue than to the other colors, it is necessary to use some means.
