Quantum Mechanics:

Define degeneracy and explain why it becomes possible for the 2D and 3D particle in a box (PIB).

Determine the degeneracy of a 3D PIB energy level.

Explain why it is possible for the "particle" to get through a node in a wave function to get to the other side of the box.

Explain why the wave function for the 3D PIB appears as a product in the form of X(x)Y(y)Z(z)
