le are added, until at a sufficiently hightemperature the solid becomes luminous, i. e. radiation of wave-length shorter than 7-6 x io-6 cm. is produced, so that the eyeis affected by it. When the temperature is still further raised,the phenomena proceed in a similar manner: the intensity ofthe red… … in the lower. The distribution of energy in the spectrum willbe more easily grasped from the curves in Fig. 97. The heightof the curve there represents the intensity of the radiation ofthe particular wave-length, as shown by the abscissae, and as measured by puttinga sensitive thermo-meter in the…
