1) Consider the following example of a quantum mechanical
wavefunction for a particle of mass m moving in one dimension,
where α and A are constants.
?(?, ?) = ?? − ?(?2 + ?ℏ?/?) ,
a) Normalize the wavefunction. Show your work.
b) At what value of x is there equal probability for the particle
to be either to the left or to the right of that x? Show your work
and explain.
c) For the wavefunction given, what must the potential V (x, t) be
in order for Ψ(x, t) to satisfy the Schrodinger equation? What
classical system has this kind of potential?
d) Calculate the expectation values of x, x2, p, and p2. Explain in
words what each calculation means (how it is related to
measurement).
e) Determine ?! and ?" and check if their product is consistent
with the uncertainty principle.
