Consider the splitting of the n=2 and n=3 energy levels for a hydrogen atom placed in a 2T
magnetic field. Consider only the normal Zeeman effect (ignore spin). (a) What is the separation
in energy between adjacent ml levels for the same l? (b) How many different...
This could be one of those questions where I'm hindered by my lack of knowledge on the subject, being only a freshman in college, but recently we learned the uncertainty principle which states that:
ΔE*Δt ≥ h/4π
Given this, I'm assuming it'd be accurate to rewrite ΔE as Δm*c2, which would...
Ah, yes, I'm using "guessing" in the the sense that as I'm learning differential equations, the book tells us to "guess" solutions to the second order differential equations. It's not really guessing, but I've gotten used to the term.
Thanks so much!
Oh I see. So if the particle is bound by the potential, we know V > E, so we "guess" the exponential solution. But if the particle is free and E > V, then we guess the sinusoidal solution? Is that the correct interpretation?
So I get that it will be the same as the function for a < x < b except that the constants in front of the sine/cosine will be different and k = √2m(E - Uo)/ (hbar)2?
Is that right?

What is the functional form of the wave function in the ground state in the
five regions x<0, 0<x<a, a<x<b, b<x<L, and x>L?
I've attached the picture of the potential well as well here:

Homework Statement
We are the given the rare decay:
π+ → e+ + ve
Also, we are given mπ = 139.6 MeV/c2, mv ≈ 0, me+ = 0.511 MeV/c2
And we are given that the decay starts with the pion at rest, so I took that to mean that pπ = 0
Solve for the momentum of the positron.

Thanks for your help! I don't think I did it the way you were telling me, but the output was the same. Here was my final code:
SO2.a = 38.91; SO2.b = 3.904*10^-2; SO2.c = -3.105*10^-5; SO2.d = 8.606*10^-9;
SO3.a = 48.50; SO3.b = 9.188*10^-2; SO3.c = -8.540*10^-5; SO3.d = 32.40*10^-9;

I apologize, I really do, but I'm not entirely sure how to do what you are talking about. The problem I seem to be having is that every time the user puts in the reply of 'Y', and inputs a new T1 (hence creating a new Cp2), it seems to overwrite the previous one. Thus, when I display the end...
Hi, thank you for replying! I've fixed my problem that it kept closing after running the script, but at the moment I've got this:
while reply == 'Y'
T1 = input('Input another temperature: ');
Cp2 = inputval.a + inputval.b*T1 + inputval.c*(T1)^2 + inputval.d*(T1)^3;
Table1 = [T1 Cp2];reply =...
