Absolute reflectance measurements allow determining the true reflectance of samples, which is referred to as absolute … WebSep 7, 2024 · Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light. Since absorptivity equals emissivity by Kirkhoff's Law, that is also low for metals. The absorption of light can happen due to lattice vibrations and excitation of electrons to higher energy levels.
