When a hydrogen atom undergoes a transition from the n=2 state to the n=1 level, a photon
with [tex]\lambda[/tex]=122nm is emitted.
a)If the atom is modeled as an electron in a one-dimensional 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?
