Black body radiation phenomenon

WebJul 7, 2024 · In physics, Black body radiation is a phenomenon in which an object absorbs all electromagnetic waves that fall upon it. Unlike the name, a black body doesn’t need to be black in colour but for the body to stay in an equilibrium state it should emit the absorbed radiation too. WebTo stay in thermal equilibrium, a black body must emit radiation at the same rate as it absorbs, so it must also be a good emitter of radiation, emitting electromagnetic waves of as many frequencies as it can absorb, …
