Revise AQA GCSE Physics 6.3.1 Emission and absorption of infrared radiation with the question bank, lessons, revision guides, and flashcards.
All bodies (objects), no matter what temperature, emit and absorb infrared radiation. The hotter the body, the more infrared radiation it radiates in a given time. • A perfect black body is an object that absorbs all of the radiation incident on it. A black body does not reflect or transmit any radiation. Since a good absorber is also a good emitter, a perfect black body would be the best possible emitter.
