    Help with a concrete question about the Franck-Hertz experiment

    I'm studying the Franck-Hertz experiment for my Quantum Physics class, and I don't see why the minimums for the graphic U_1 (accelerating voltage) vs I_a (collector intensity) increase. It seems logical, but I can't find a proper explanation. If anyone could help me it would be great :)...

    Graduate Number of invertible/non-singular matrices over a finite field

    Thanks a lot for the quick reply! I solved it already :) Hadn't thought about the cardinal of GL_n(\mathbb{F}_q) Thanks!

    Graduate Number of invertible/non-singular matrices over a finite field

    I'm trying to find the number of different non-singular matrices (nxn) over a finite field (order q). Any help would be greatly appreciated. Thanks in advance! :)
