-A blackbody is an idealized physical body that absorbs all the radiation incident on it, at all wavelengths.

-Hence, a blackbody is a perfect or ideal absorber.

-A blackbody also emits energy in all regions of electromagnetic spectrum.

-Hence, a blackbody is also a perfect or ideal radiator/emmiter.

-The value of e for a blackbody is 1.
