WebbA law closely related to the blackbody is Kirchhoff’s law that defines reflection, transmission, absorption and radiation. α + ρ + τ = 1. where, α : absorptance ( = ε : emissivity) ρ: reflectance. τ : transmittance. Also, absorptance equals emissivity, and so emissivity can be described by reflectance and transmittance.
