What is Maxwell Distribution, Thermal Equilibrium, Fluctuation and Wein's law?

AI Thread Summary
Maxwell Distribution describes the statistical distribution of speeds of particles in a gas at thermal equilibrium. Thermal equilibrium occurs when a system's temperature is uniform, leading to consistent energy distribution among particles. Fluctuations refer to temporary deviations from this equilibrium state, which can impact particle behavior. Wien's law relates the temperature of a black body to the wavelength at which it emits radiation most intensely. Understanding these concepts is crucial for grasping Einstein's explanation of the photoelectric effect and the fundamentals of quantum theory.

I was reading a book, 'Introducing Quantum Theory' by J.P.McEvoy, and I find it difficult to understand in details of Maxwell Distribution, Thermal Equilibrium, Fluctuation, Wein's law and Planck's quantum theory, so I am finding it difficult to follow Einstein's explanation of photoelectric effect. Can someone explain the following things I listed above, from scratch to top, including the explanation of graphs?

OK My question was too vague. I will ask much more specific question.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
