Homework Help: Quantum Physics - Infinitely vs Finite depth quantum well

  1. Apr 21, 2016 #1
    1. The problem statement, all variables and given/known data
    Comment how the energy and wave functions of the electron would change in the case of a finite dept quantum well with the same width.

    2. Relevant equations

    3. The attempt at a solution
    I feel completely clueless as how to approach! :(

    * The full question can be found in the uploaded image below, thanks so much!

    You need to write the Schrodinger equation and look for solutions with boundary conditions. For finite well probability of existence of electron out side the well will be non-zero whereas for infinite well the probability will be zero. Wave function will be sinusoidal inside and outside it will be zero for infinite well. look up for a good reference book and work on these problems. See how Heisenberg principle is also obeyed for both of these.
