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

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...

In Atkins's physical chemistry textbook it is written that 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...
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.
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:

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?
