Energy of the first excited state
Consider an electron in a box. If the energy of the first excited state is 10 eVlarger than the energy of the ground state, what is the size of the box.

Apply boundary conditions to obtain the minimum energy of the electron in this box. Compare this energy with that of the n = 10 state of hydrogen.
