{wiki=Black_body}
A black body is an idealized physical object that absorbs all incoming radiation, regardless of the frequency or angle of incidence. In other words, a black body is a perfect emitter and absorber of thermal radiation.

Key characteristics of a black body include: 1. **Absorption**: A black body absorbs 100% of the electromagnetic radiation that falls on it.
