When a hydrogen atom undergoes a transition from the n = 2 to the n = 1 level, a photon with l = 122 nm is emitted. (a) If the atom is modeled as an electron in a onedimensional box, what is the width of the box in order for the n = 2 to n = 1 transition to correspond to emission of a photon of this energy? (b) For a box with the width calculated in part (a), what is the groundstate energy? How does this correspond to the groundstate energy of a hydrogen atom? (c) Do you think a onedimensional box is a good model for a hydrogen atom? Explain. (Hint: Comp
