✦ Synopsis

427 3. Watts radiated per unit surface. 4. Watts exponent, nw= d log lV/d log T where W= watts radiated at o ° K.

5-Total emissivity. (Watts radiated as fraction of total radiation from a black body at the same temperature.)

6. Intrinsic brilliancy per square centimetre of projected area. 7. Color expressed as temperature of a black body which emits light of the same color.

The mechanical equivalent of light, using Nutting's visibility data and taking as constants of the Planck equation C1 = 3.72 X IO "''~ watts C, z 1.4392
