WebApr 4, 2024 · A blackbody absorbs all incoming light (or any electromagnetic radiation) and converts the light's energy into thermal energy. No electromagnetic radiation is reflected. The energy radiated by the object as EM waves is based solely on its temperature. Most objects do reflect light, allowing one to see them. http://www.mhtl.uwaterloo.ca/courses/syde381/lectures/summary/summary_ch15_S14_381.pdf
