In particular, Planck assumed that electromagnetic radiation can be emitted or absorbed only in discrete packets, called quanta, of energy: Estratto da ” https: Per un gas biatomico:.

Ultraviolet catastrophe – Wikipedia

By using this site, you agree to the Terms of Use and Ulttavioletta Policy. The term “ultraviolet catastrophe” was first used in by Paul Ehrenfestbut the concept originated with the derivation of the Rayleigh—Jeans law. This therefore implies that the radiated power per unit frequency should catastroe the Rayleigh—Jeans law, and be proportional to frequency squared. Thus, both the power at a given frequency and the total radiated power is unlimited as higher and higher frequencies are considered: And, since each mode will have the same energy, most of the energy in a natural vibrator will be in the smaller wavelengths and higher frequencies, where most of the modes are.


Ad esempio, per una mole di gas monoatomico risulta:. Planck’s assumptions led to the correct form of the spectral distribution functions: Vedi le condizioni d’uso per i dettagli. Albert Einstein and Satyendra Nath Bose solved the problem by postulating that Planck’s quanta were real physical particles — what we now call photonsnot just a mathematical fiction.

For his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.

In classical physics, a radiator uotravioletta energy will act as a natural vibrator. Retrieved from ” https: According to classical electromagnetism, the number of electromagnetic modes in a 3-dimensional cavity, per unit frequency, is proportional to the square of the frequency.

A History of the Sciences. Si consideravano i corpi composti da un numero enorme di oscillatori indipendenti con hamiltoniana del tipo: Max Planck derived the correct form for the intensity spectral distribution function by making some strange for the time assumptions. Einstein’s photon had an energy proportional to its frequency and also explained an unpublished law of Stokes and the photoelectric effect. Questo evento prese il nome di catastrofe ultravioletta dato che erano proprio questi il tipo di raggi che dovevano essere emessi dai corpi a temperature ordinarie i raggi UV, i raggi X e i raggi gamma.
