Hey, not sure if this should go here or not but it seemed the best place. I'm trying to find a rotating table and a motor for a doppler shift experiment a lot like the one on page 4 of this website: http://academic.reed.edu/physics/courses/phys100/Lab%20Manuals/Doppler%20Effect/Doppler.pdf...

Thanks for that.

Homework Statement I have to calculate the approximate electrostatic potential far from the origin for the following arrangement of three charges: +q at (0,0,a), -q at (0,a,0) and (0,-a,0). I have to give the final answer in spherical coordinates and keep the first two non-zero terms in the...

I would think the integral of Q1Q2* would be zero since these wavefunctions are orthogonal, so I would end up with C^2 =5/20.

Well there aren't any imaginary parts to the first wavefunction since its just in the form Q = C ( XQ1 - YQ2) so Q* is just the same as Q.

they follow linear superposition? so the integral of the total wavefunction squared is equal to the integral of 1.6*Q1^2 plus the integral of 2.4*Q2^2?

Homework Statement A one-dimensional system is in a state at time t=0 represented by: Q(x) = C { (1.6^0.5)Q1(x) - (2.4^0.5)Q2(x)} Where Qn(x) are normalised eergy eigenfunctions corresponding to different energy eigenvalues, En(n=1,2) Obtain the normalisation constant C The...

Thanks, got it now.

1. The problem Statement A cubic box of volume V=L^3 contains energy in the form of photons in equilibrium with the walls at temperature T. The allowed photons energies are determined by the standing waves formed by the electromagnetic field in the box. The photon energies are (h/2pi)Wi =...

Thanks, that's what I did, but it just seemed a bit wrong to me. Maybe because I thought there was more to it. Anyway, thank you.

Sorry, another quick question. If I have a particle confined in a region of space -4 <= Z <=6 where psi(x)= A(4+z), -4<= z <=1 A(6-z), 1<= z <=6 0 , everywhere else And I sketch the wavefunction based on the above definitions, what is the actual equation for...

Ok thanks, you've really helped me out, the website was especially helpful.

The radius comes in when we look at the wavefunctions across x=a, where they should be continuous, so psi1=psi2 and dpsi1/dx=dpsi2/dx. I have to divide one by the other to get a solution in the form -y=xcot(x), then rearrange the circle equation to get y, sub it in and the intersection gives the...

My head's melting right now, because I've been stuck on this for the past 6 hours. There's a particle of mass moving in a potential well where V(x) = infinity at x<0 V(X)=0, 0<x<a V(x)= Vo, x>a Vo>0 E<Vo I'm assuming that the wavefunction at x<0 is 0, since there's an infinite...
