An electron of energy E = 1.5 ev is incident from the left on an infinitely thick barrier of height V =1 ev. E=1.5 ev V=1 eV V=0 x = 0 (1) Solve for the wavefunction everywhere. (2) What is the amplitude of the reflection for the wavefunction? Is it equal to zero like the classical case? (3) Use Matlab, Mathematica or Excel to plot the resulting probability density P(x), and give explicit values for any key distances in your plot. For the plot, you can assume that the amplitude of the incident wavefunction is unity.
