if a blackbody gives of light in the form of photons, then how can it still be considered to be a blackbody?

does a blackbody convey em energy into photonic energy, but then does not light have a dual nature (packet and wave). i am confused.

A black-body is named such because not only is it a perfect radiator, it also is a perfect absorber of radiation. If such a thing existed it would be utterly dark when cold. For simplicity, many things are treated as if they were black body radiators in calculations.

thanks for the reply,

so it is a perfect radiator and a perfect absorber of radiation.

are these phenomena not contradictory. perfect radiator and perfect absorber at the same time?
