1. Apply the boundary conditions to the ?nite square- well potential at x = 0 to ?nd the relationships between the coef?cients A, C, and D and the ratio C/D.
2. Apply the boundary conditions to the ?nite square- well potential at x = L to ?nd the relationship between the coef?cients B, C, and D and the ratio C/D.
3. Find the energies of the second, third, fourth, and ?fth levels for the three-dimensional cubical box. Which energy levels are degenerate?
4. Write the possible (unnormalized) wave functions for each of the ?rst four excited energy levels for the cubical box.
