Good absorbers are good emitter
Did you know?
Web- according to Kirchhoff's law, good absorbers at a particular wavelength are good emitters at the same wavelength - thus the LW radiation that is absorbed by atmospheric greenhouse gasses is emitted, thus the earths surface and lower atmosphere are warmed . WebBlackbody radiation is referred to the spectrum of light that is emitted by a heated object. For a body to stay in a thermal equilibrium state, it must emit radiation equal to the amount of the radiation it absorbs. The body must act as a good absorber and a good emitter at the same time at an equal rate.
