1. ### Probability distribution of stationary Schrodinger equation

Homework Statement Stationary Schrodinger equation for a particle moving in a potential well has two solutions psi1(x)=e^-ax^2 with energy E1 and psi2(x)xe^-ax^2 with energy E2 At t=o, the particle is in the state psi(x)=psi1(x)+psi2(x) Calculate the probability distribution as a...
2. ### Wave functions and probability

I was paying attention in the derivation, i just found it a bit hard to follow. Thankyou for your help, I'll the question another go.
3. ### Wave functions and probability

No, i copied the question down word for word, it says that the wave function is normalised! I'm sorry, I'm still very confused because it says in my lecture notes that i have to integrate to find the probability. Can you please tell me where you get |\psi|^2 dV = |\psi|^2 4\pi r^2 dr from?
4. ### Wave functions and probability

Homework Statement I've had lectures on the theory of this topic, but I've not been given any examples and I'm struggling with how to apply the theory to this homework question: A particle is described by the normalised wave function Si(x,y,z)=Ae^-h(x^2+y^2+z^2) where A and h are real...
5. ### De broglie wavelength

Thanks for clarifying that, i think i do it now. :)
6. ### De broglie wavelength

Thanks for your help. Sorry if this is a stupid question, but I've never seen that equation before, where does it come from? What does T stand for?
7. ### De broglie wavelength

Sorry if I put this in the wrong thread! For a photon, wavelength is just lambda=h*c/energy. I think for an electron you use the relativistic equation lambda=h/mv*sqt(1-v^2/c^2). I've tried equating these, but i ended up with a horrible equation to solve because i don't have velocity of the...
8. ### De broglie wavelength

How do you calcuate at what energy do a photon and an electron have the same de broglie wavelength?
