🧠 The Ideal Absorber and Emitter
A "black body" is a conceptual ideal in physics. It's an object that absorbs 100% of the electromagnetic radiation falling on it, regardless of frequency or angle of incidence. Because it absorbs everything, it must also be the most efficient emitter of radiation to maintain thermal equilibrium.

🗺️ Evaluating the Black Body Postulates
Let's dissect each statement based on the Planck and Wien laws:
- (A) Emit or absorb energy as EM radiation: This is the fundam
