2. (10 ) Consider a particle in a two dimensional box of length 1/2b in the x direction and b in the y direction; i.e. the dimensions are: 1/2bb Drawa diagram containing the lowest 6 energy levels* of a particle in a two dimensionatbox of dimensions 1/2bb. Put the energies in units of h2/8mb2, and give the degeneracy of each level. (*Note: A doubly degenerate level veuld count as only 1 of the 6 levels) (b) The 10 electrons in naphthalene can be treated as particles in a two dimensional box of dimensions 1/2bb, where b=8A. Use your diagram above to calculate the wavelength, in A, of the lowest energy electronic transition in naphthalene
