on wikipedia I found a reasonable explanation for \lambda minim i.e. \nu maxim. How to get to \nu maxim was what actually puzzled me in the beginning: There is a minimum possible wavelength, given by twice the equilibrium separation a between atoms. As we shall see in the following sections...

yes, i do it works that way and thank you very much. I solved it too with a geometrical argument on the trig circle, but i like your approach much better.

Homework Statement Hecht in his optics mentions that Asin(kx-wt+pi) is equivalent to Asin(wt-kx) w=greek omega Homework Equations What is the fundamental reason behind this? The Attempt at a Solution I have a hunch it's plain trigonometry applied, but none of the things that I can...

are you saying that even nu max is directly obtained from the formulas below? this is most of my concern how is the upper frequency limit set? thank you btw :smile:

Homework Statement [/b] Debye considered atoms to oscillate from 0 up to a nu max. It is explained further in the text that the complication (i.e., not all atoms oscillating at same frequency as shown in Einstein's formula) is accounted for, by averaging over all the frequencies present...

Why is the s,p,d,.. nomenclature derived for the H atom also valid for many-electron atoms?

why is there an upper limit to the photon energy that can be observed in the emission spectrum of the hydrogen atom?

Aha...well I never dragged it one step further. I hope you're right because I will take what you say for granted for now.

everything you mention does not fit my definition of a process.

that's really more towards my chemical plate, i never thought of phase trasitions. i am not sure what you mean by caustics but i will look it up.

Well if you look at the graphs that's not exactly what seems to happen. You might need to zoom in on time to understand that it's continuous. I don't think acceleration can be considered a discontinuous process.

I am wondering if there are any discontinuous processes in nature and which are they, if any. thank you.

Ok well I was reading through another textbook (Halliday Resnick Walker) and things are a little clearer now. This is part of what I was looking for: startquote: Although the total charge on the capacitor is zero (because there is as much excess positive charge on one conductor as there is...

Thank you for trying to help. I still don't understand how the plates are charged. I also don't understand if this charge creates or requires a potential energy?

Hello, I don't understand how my general physics textbook describes how energy is stored in a capacitor. Can someone please explain this? One of the details I don't understand is who comes first? Is it the potential difference that creates charge accumulation,or is it charge accumulation...
