tants in equations (78) and (81) have once been determinedthe equations can be used for the measurement of the tempera-ture of radiating bodies, either by measuring the rate of radia-tion or by locating the wave length corresponding to the energymaximum in the spectrum. RADIATION. 255 The… … Fig. 162. are inapplicable. It should, however, be kept in mind that theabove equations hold strictly only for black body radiation; theblack body temperature calculated from the formula may besomewhat smaller than the real temperature. The differences are,however, relatively not very large for…
