Put an electron (m = 9.1 × 10-28 g) in a one-dimensional box of length 2 × 10-8 cm. This is approximately the size of an atom.
(a) Compute the lowest possible energy, E1. This is the zero-point energy.
(b) Determine the energy of a photon corresponding to the absorption transition from state n = 1 to state n =
2 . Compare this transition energy to that for a hydrogen atom for then=1→2 transition. !
