The connection between emissivity and albedo is defined by the equation emissivity + albedo = 1 for opaque objects. Emissivity is equal to albedo at a specific wavelength, ensuring that heat transfer via radiation adheres to the second law of thermodynamics. The discussion clarifies common misconceptions, particularly the distinction between emissivity, albedo, and absorption. Spectral weighting may also play a role in the definition of albedo.

Andy Resnick said:Albedo is a reflection, so emissivity + albedo = 1, for opaque objects. There's probably some spectral weighting involved in the definition of albedo.
