SUMMARY

The discussion focuses on sketching the wave-function of a particle in its ground state based on the provided potential graph. Participants reference Schrödinger's Time Independent equation, emphasizing the importance of accurately depicting the wave-function, particularly the curvature and peak locations. A specific suggestion was made to adjust the peak of the wave-function and ensure the rightmost section curves upwards, correcting any downward curvature that may extend beyond designated boundaries.

PREREQUISITES
  • Understanding of Schrödinger's Time Independent equation
  • Familiarity with wave-functions in quantum mechanics
  • Knowledge of Hamiltonian Operators
  • Ability to interpret potential energy graphs
NEXT STEPS
  • Review the principles of wave-function normalization
  • Study the implications of potential energy shapes on wave-functions
  • Learn about quantum measurement and probability density functions
  • Explore graphical techniques for representing quantum states
USEFUL FOR

Students of quantum mechanics, physics educators, and anyone involved in theoretical physics or quantum state analysis will benefit from this discussion.

Homework Statement



I am given the graph of the potential of a particle, and the particle is in its ground state. I must make the graph of the wave-function with respect to x.

(A) Sketch psi(x) for this particle.
(B) You make a measurement to find the particle. Indicate on your graph the point or points at which you are most likely to find it.


Homework Equations



Schrödinger's Time Independent equation with the second partial derivative with respect to x of the wave-function on the left-hand side and the Hamiltonian Operator on the right hand side.

The Attempt at a Solution



In the attached image. I just want to know if anything is incorrect, or if I am missing something, so that I don't do the rest of the questions fundamentally incorrectly. Thank you!

That looks almost right to me. :smile:

Expect for one thing, you might want to move the peak of the curve indicated by point B just a touch.

The rightmost section of the wavefunction (right of the rightmost dashed, vertical line) should be curving upwards. But the way you've drawn it, some of the downward curvature from the previous section (The section containing B) looks to have crept over the dashed line.
