In quantum mechanics, radiation means that massless particles called photons carry energy away from the body. All electromagnetic radiation (including visible light) consists of photons. Each photon carries energy equal to hc/ , where is the wavelength of the photon, h is the Planck constant (6.6 x 10-34 Joule-sec in SI units), and c is the speed of light. Blackbody radiation is given by the Planck Distribution Function, which says that the
