Consider a two-dimensional squared-well of dimensions L × L. The length L is such, that the ground state energy of one electron confined in this box is 0.1eV.

(a) Write down the 5 lowest energy states and their corresponding degeneracy (your energy values must all be different!) and label them E1 · · · E5

(b) If the electron finds itself in one of the states with energy E5, how much energy would be required to lift the electron from E5, to the next lowest energy level E6?

Please explain how you get the ground state and 1st , 2nd,... excited state energies.
