Unformatted text preview: radiation as a function of frequency for a fixed temperaturethe result is known as the RayleighJeans law. Although the RayleighJeans law works for low frequencies, it diverges as ; this divergence for high frequencies is called the ultraviolet catastrophe. Max Planck explained the blackbody radiation in 1900 by assuming that the energies of the oscillations of electrons which gave rise to the radiation must be proportional to integral multiples of the frequency, i.e., (1) Using statistical mechanics, Planck derived an equation similar to the RayleighJeans equation, but with the adjustable parameter . Planck found that for J s, the experimental data could be reproduced. Nevertheless, Planck could not offer a good justification for his assumption of energy quantization. Physicicsts did not take this energy quantization idea seriously until Einstein invoked a similar assumption to explain the photoelectric effect....
