Black Body Radiation: Definition, Application, Graph StudySmarter

WebBlackbody radiation is a term used to describe the relationship between an object's temperature, and the wavelength of electromagnetic radiation it emits. A black body is an idealized object that absorbs all electromagnetic radiation it comes in contact with. It then emits thermal radiation in a continuous spectrum according to its temperature. WebThis is called black body radiation. The amount of heat radiated by a body, the power, is given by Stefan's constant (σ) multiplied by the surface area of the body (A) multiplied by the emissivity of the body (e, which is a number between 0 and 1 and is related.
