Homework Help Overview

The discussion revolves around the normalization of a wavefunction represented by the expression sin(θ)e^(-iφ). Participants are exploring the setup of integrals necessary for this normalization process, particularly in the context of polar coordinates.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the general form of normalization integrals and the need to switch to polar coordinates. There are inquiries about the correct setup of the integral and the bounds for integration. Some participants express uncertainty about their attempts and seek confirmation on their approaches.

Discussion Status

The discussion is ongoing, with participants sharing their attempts at setting up the integral and questioning the correctness of their bounds. Some guidance has been offered regarding the general form of normalization, but there is no explicit consensus on the specific setup or resolution of the issues raised.

Contextual Notes

There are indications of confusion regarding the limits of integration and the inclusion of variables in the integral setup. Participants are also navigating the implications of leaving out certain components, such as the radial part of the integral.

how to set up integrals for normalization of sin([itex]\theta[/itex])e^(-i[itex]\phi[/itex])

Can you give any more detail as to what you're doing? In general a normalized wave function would work along the following lines

[itex]\int[/itex][itex]\Psi[/itex](x)*[itex]\Psi[/itex](x)dx=1

or

[itex]\int[/itex]|[itex]\Psi[/itex](x)|2dx=1

with the limits of integration being from -[itex]\infty[/itex] to +[itex]\infty[/itex]
 
I know it needs to be switched to polar coordinates and your equation you posted is correct. I know that it is normalizable (1=int(psi^2dv) over all space, i just need a confirmation of the correct set up of the integral and the bounds. I've tried it several different ways with different bounds and I haven't gotten it to be one.
 
anyone?
 
You need to show what you've tried so that we can help you identify where you're going wrong. When you don't do that, many people will simply ignore your thread. See the https://www.physicsforums.com/showthread.php?t=94380.
 
Ok I've set up the integral like this:[itex]\oint[/itex]sin[itex]^{3}[/itex][itex]\theta[/itex]*dv with the bounds being 0 to 2pi for phi, and 0 to pi for theta. I left out r because it will make the integral go to infinity, but I'm still getting a pi in the answer. when I left out the phi part of the integral I got 4/3. what am I doing wrong?
 
For starters, how do you know you're doing something wrong?
