A black body is a body or surface which is not reflective at all. In other words, a black body is a body with absorptivity of 1 and hence it absorbs the entire radiation without reflecting any (Howard, 2000). On the other hand, a grey body refers to a body that reflects some of the radiation and hence its absorptivity is less than 1.
