In a graph of blackbody intensity as a function of frequency, this formula is depicted sloping up towards the "ultraviolet catastrophe," and with Wien's law it is one of the limiting factors of Planck's law.
It can be derived classically and does not apply at high energies when the quantum nature of photons must be taken into account. In a graph of blackbody intensity as a function of frequency, this formula is depicted sloping up towards the "ultraviolet catastrophe," and with Wien's law it is one of the limiting factors of Planck's law. The reason for this limitation is that it does not take Planck's constant into account. FTP, identify this classical representation of blackbody radiation named after the two physicists that collaborated on its development.
