A finite potential well has depth U0=5.5 eV. In the well, there is an electron with energy of 4.0 eV.
a. What is the penetration distance of such electron?
b. At what distance into the wall has the amplitude of the wave function decreased to 60% of the value at the edge of the potential well?
c. If the depth of the well and the energy of the electron both increase by 0.5 eV, will the results for the question (a) and (b) change? Why or Why not?
d. If the particle is a proton instead of electron, will the penetration distance increase or decrease? Explain.
