WebJul 3, 2014 · White reflects most of the energy falling from the visible spectrum, black absorbs it. When the energy of light is absorbed it turns into heat . Any material painted black will absorb this heat further and its temperature will be raised but it will depend on the material how far the heat is transferred. If it is metal painted black, metal is a ... Webwhere, B(T) represents blackbody radiation or spectral emissivity at a particular wavelength and temperature. If the wavelength is taken in nanometers (nm) and temperature in Kelvins (K), the units of blackbody radiation will be Watts per meter squared per nanometer (W / m 2 / nm),. c is the speed of light which is c=2.99792458 × 10 8 measured in meters …
