Probability distribution plots

Click For Summary

Discussion Overview

The discussion revolves around the plotting of probability distribution functions related to quantum mechanics, specifically for Ψ, Ψr², and r²Ψ versus r for both Ψ²s and Ψ²p orbitals. The scope includes conceptual understanding and application in a homework context.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant expresses frustration over an assignment related to plotting probability distributions, indicating uncertainty about the requirements.
  • Another participant suggests that the lecturer likely provided explicit expressions for the wavefunctions, implying that this information is crucial for the task.
  • A different participant emphasizes the need for clarification from the lecturer regarding the assignment to facilitate better assistance.
  • One participant mentions their understanding of needing to plot the probability density curve, specifically Ψ²r² versus r.
  • There is a challenge from a participant who interprets the request as an expectation for them to do someone else's work, leading to a defensive response.
  • Subsequent replies indicate that the original poster has found solutions after following advice, suggesting some resolution to their initial confusion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specifics of the assignment or the best approach to plotting the required functions. There are mixed responses regarding the expectations of the task.

Contextual Notes

There is a lack of clarity regarding the exact requirements of the assignment from the lecturer, which may affect the participants' ability to provide targeted help.

hi, so my lecturer decides to give me manic depression by sending me on a wild goose chase. what is the general form of a plot of Ψ, Ψr2 and r2Ψ versus r for both Ψ2s and Ψ2p orbital... am not even sure i said it right

Not sure why this would make you depressed. Presumably he also derived an explicit expression for those wavefunctions?

(In any case, you should probably clarify exactly what your lecturer wants -- in writing -- since otherwise it's hard to help you.)

After which its likely better in the homework help section.

Thanks

Thanks. Guys
 
Strangerep he needs me to draw the p.d curve... to the best of my knowledge i only know if psi squared r squared versus r

!? I "need to"?? Hmm, we're not here to do your work for you. Bye.
 
No... i meant the lecturer did... but I've followed your advice and gotten the solutions... thanks
