alleryStart learning →Which statement about absorbers and emitters of radiation is correct?
AGood absorbers are always good emitters
BGood absorbers are poor emitters
CGood reflectors are good emitters
DEmission is unrelated to absorption
Answer & Solution
Correct answer: A. Good absorbers are always good emitters
To stay at constant temperature a surface must emit as fast as it absorbs, so a good absorber is also a good emitter.
