SUMMARY
Black-body radiation refers to electromagnetic radiation emitted by a body in thermodynamic equilibrium with its surroundings. The discussion emphasizes that thermodynamic equilibrium is crucial for understanding the net absorption and emission of light. When a body is not in thermodynamic equilibrium, the rates of absorption and emission of radiation differ, leading to a net change in energy. This imbalance affects the thermal properties and behavior of the body in question.
