![]() As the temperature of an object increases, there is an increased probability of emitting radiation with higher frequencies, corresponding to higher-energy quanta. Basically, Plancks work led Einstein in determining that light exists in discrete quanta of energy, or photons. ![]() ![]() The theoretical radiancy emitted by a blackbody versus the wavelength at several temperatures. The change in intensity of a light beam due to absorption as it traverses a. We can understand Planck’s explanation of the ultraviolet catastrophe qualitatively as follows: At low temperatures, radiation with only relatively low frequencies is emitted, corresponding to low-energy quanta. where c is the speed of light in a vacuum, h is Plancks constant, k is Boltzmanns constant, T is the absolute temperature of the body, and is the wavelength of the radiation (Fig. The equation of radiative transfer states that for a beam of light going. ![]()
