Homework Help Overview
The discussion revolves around proving the expectation value of an eigenvalue function in quantum mechanics, specifically focusing on the calculation of the expectation value of position, , for a particle in a box potential.
Discussion Character
- Exploratory, Assumption checking
Approaches and Questions Raised
- The original poster attempts to compute the expectation value using integration but encounters a result of 0 instead of the expected L/2. This leads to questions about the formulas and integration limits being used. Participants inquire about the integration limits and the size of the box in which the particle is confined.
Discussion Status
Participants are actively questioning the assumptions regarding integration limits and the physical setup of the problem. Some guidance has been offered regarding the confinement of the particle, but no consensus has been reached on the correct approach or resolution of the original poster's issue.
Contextual Notes
There is an ongoing discussion about the appropriate integration limits, which are suggested to be from -infinity to +infinity, and the size of the box, which is confirmed to be from 0 to L.
