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. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena, as … Spectrum Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law. The spectrum is peaked at a characteristic frequency that shifts to higher frequencies with increasing temperature, and at … See more Black-body radiation is the thermal electromagnetic radiation within, or surrounding, a body in thermodynamic equilibrium with its environment, emitted by a black body (an idealized opaque, non-reflective body).

WebMay 19, 2016 · Add a comment. 0. A black-body can absorb all the radiation falling on it (light at all wavelengths) and appears black when cold. When it gets heated it can emit radiation at all wavelengths like a heated piece of metal. The hotter it gets the higher the photon frequency (energy) and so a shorter wavelength.
