Homework Statement 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?

Okay I think I see that. But how do we determine if the wavefunction will be sinusoidal or exponential?

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?

Homework Statement 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 Equations Schrödinger time independent equation The Attempt at a...

Homework Statement Laser can now be designed to emit pulses of light smaller than 30 microns wide in their direction of motion. (a) Estimate the uncertainty in the momentum of a photon in such a pulse. (b) The momentum of a photon is p=h/λ. Estimate the uncertainty in the...

Homework Statement A 400-gallon tank initially contains 200 gallons of water containing 2 parts per billion by weight of dioxin, an extremely potent carcinogen. Suppose water containing 5 parts per billion flows into the top of the tank at a rate of 4 gallons per minute. The water in the tank...

Homework Statement A meter stick moves parallel to its length with speed v = 0.6c relative to you. a. Compute the length of the stick measured by you. b. How long does it take for the stick to pass you? Homework Equations t = to*γ L = Lo/γ The Attempt at a Solution Part a was...

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. Homework Equations...

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; O2.a...

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 =...

Homework Statement Write a program that does the following: Prints the four gases on the screen and asks the user to select which gas to find the heat capacity for. Asks the user for a temperature. Asks the user if another temperature is needed (enter yes or no). If the answer is yes...
