Which law signifies that good absorbers are a good emitter? Correct Answer Kirchhoff’s Law
According to Kirchhoff's Radiation Law good absorbers are good emitters. For a body of any arbitrary material emitting and absorbing thermal electromagnetic radiation at every wavelength in thermodynamic equilibrium, the ratio of its emissive power is equal to a universal function only of radiative power.
