Explanation:
Detailed explanation-1: -A blackbody is defined as an ideal body that allows all incident radiation to pass into it (zero reflectance) and that absorbs internally all the incident radiation (zero transmittance). From: Encyclopedia of Physical Science and Technology (Third Edition), 2003.
Detailed explanation-2: -What is meant by black body radiation? The radiation emitted by the blackbody is known as blackbody radiation. To stay in thermal equilibrium, a black body must emit radiation at the same rate as it absorbs, so it must also be a good emitter.
