Dotted curves indicate distribution from artificial sources, , radiation from 100-watt tungsten lamp, at approximately 2755° K., same through 3-cm. water cell, through 3-cm. water cell and the following filters (all heat-resisting, heat-absorbing): extra light shade, mm. (thickness); light shade, mm.; light medium shade, mm.; dark medium shade, mm.; dark shade, mm. (From data of Abbot, 4.) These curves do not give any idea of the wave-length distribution below 4000 A, , in the ultra-violet. From 1 to 5 per cent of the energy occurs in this region. A typical distribution curve of relative intensity for wave-lengths between 2900 and 3600 A is plotted from data of.
