The ultraviolet catastrophe

  1. May 4, 2015 #1
    Why is it called the ultraviolet catastrophe rather than the visible catastrophe or the microwave catastrophe?

    A simple internet search tells me that the measured curve as predicted by Plank's Law peaks in the ultraviolet rather than going on to infinity as predicted by the classical Rayleigh-Jeans Law and I'd guess that's why it's called the "Ultraviolet Catastrophy". You would likely find it helpful to learn how to do simple research.

    This is easy. Ehrenfest had only one option, really. X rays and Gamma rays were unknown terminology to him and he really cared about the limits of the visible spectrum. Pringsheim did measurements there.
