Philip,
Thank you for that explanation.
I understand everything you say when there is constant volume, etc,
but in that problem (first link), the B->C process has constant pressure,
and volume changes, so work is being done...
What you are saying is that for ΔU calculation for that...
Hello All, I am interpreting a diagram from the following question.
(I didnt have a chance to take thermo and I learned it by myself so I might have some problems)

I understand that I can just do ΔW and I get the right answer,
but upon doing it...
When you say a traveling and standing wave, what does that mean? That there is some standing wave pattern which is itself moving? I guess this is the part I do not get...
Hello I have a question regarding reflected light from a surface of higher index of refraction.
Suppose I have a ideal laser, and an ideal surface with reflection coefficient 0.7 or something like that.
Say I shine my laser directly perpendicular to the surface (at 90 degrees).
I...
Claude, I agree.
If I have a phase factor of e^i(pi/2) then I will just get
E = 0 ihat + E0 * -i*e^i(pi/2) jhat
= 0 ihat + E0 * 1 jhat which is what I began with
Correct me if I am wrong! but it makes sense to me as of now!
Hello, I am wondering a little about Jones matrix...
For example, If I have a Quarter Wave Plate with fast axis Horizontal, given by matrix
1 0
0 -i
and a vertically polarized light
0
1
the resultant light polarization is
0
-i
With QWP, it makes sense that if the...
Hello I have a question about coupled oscillators and what initial conditions affect what constants of integration.
In the book I have, A.P. French Vibrations and Waves, the guesses at solutions are chosen at random and sometimes do include a phase shift, while sometimes they dont.
For...
