Earth blackbody radiation
WebMar 3, 2024 · blackbody, also spelled black body, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. WebWhen a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. This emission is called blackbody radiation. A room temperature blackbody appears black, as most of the energy it radiates is infra-red and cannot be perceived by the human eye.
