What is the absorptivity of a black body?
A blackbody is an ideal object that has perfect absorption of all radiation that falls on it, regardless of direction or wavelength. It has precisely 0 reflectivity and transmissivity at all wavelengths, precisely 1 absorptivity at all wavelengths, and precisely 1 total emissivity.Feb 24, 2020
