  • ruИдеализированный физический объект, который поглощает всё падающее электромагнитное излучение, независимо от частоты или угла падения. В физике используется как теоретическая модель для изучения теплового излучения и излучения абсолютно чёрного тела.

An idealized physical object that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. In physics, it is used as a theoretical model for studying thermal radiation and blackbody radiation.

  1. Ideal physical bodyC2formal
