The total hemispherical absorptivity of electroplated silver at 75.8°K has been measured as a function of blackbody radiation temperatures from 268°K to 367°K. The measurements were made in a Dewar‐like calorimeter. The total hemispherical absorptivity is found to increase with decreasing blackbody radiation temperature. Assuming a simple relationship between hemispherical absorptivity and normal absorptivity, the normal absorptivity increases with increasing mean wavelength.
