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.
 
Thank you for your kind words.
 
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.
 

Thread 'Schrödinger equation and classical wave equation'

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Thread 'Is Maxwell's electromagnetism an effective (field) theory?'

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
