Analysis: An electron is confined to a one-dimensional space with infinite potential barriers at x = 0 and x = L and a constant potential energy between 0 and L. The electron is described by the wave function, wave function symbol=C(Lx-x2). Set up (do not evaluate) an expression that gives the energy of the system. Why is it possible to know the exact value of energy, but only the average position?
