SUMMARY

The forum discussion centers on a question from an MIT OpenCourseWare video related to quantum mechanics, specifically regarding eigenfunctions and eigenvalues. The correct answer to the posed question is identified as option B, while option C is mistakenly considered valid by one participant. Upon further analysis, it is clarified that only two combinations of eigenfunctions are applicable, leading to the conclusion that option C is indeed incorrect. The discussion concludes with the acknowledgment of a misreading of the question by one participant.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with eigenfunctions and eigenvalues
  • Basic mathematical skills for problem-solving
  • Experience with MIT OpenCourseWare resources
NEXT STEPS
  • Review the concept of eigenvalues in quantum mechanics
  • Study the mathematical derivation of eigenfunctions
  • Watch additional MIT OCW videos on quantum mechanics
  • Practice solving eigenvalue problems with pencil and paper
USEFUL FOR

Students of quantum mechanics, educators teaching quantum physics, and anyone interested in deepening their understanding of eigenfunctions and eigenvalues in the context of quantum theory.

Hey all,

So I was watching an MIT OCW video on intro QM and came across this 'clicker' question. (Shows up at 4:45)


Apparently the correct answer is B, but C looks valid to me as well. Could someone explain why C is incorrect?

Thanks

Work it out with pencil and paper carefully, and you'll see that there are only two combinations that work.

Oh wow, I seriously misread the question... Thank you. This thread should be closed probably.
