A perfect black body is a perfect _____________ of radiation?
Correct answer: C. Both A. & B.
- A. Absorber
- B. Emitter
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
A perfect black body absorbs all incident radiation and, at a given temperature, emits the maximum possible radiation. It is therefore both a perfect absorber and a perfect emitter.
