Suppose that a photon emitted by a hydrogen atom with configuration 5d causes an electron to be dislodged from the surface of potassium, k metal. what are the minimum and maximum values possible for the de broglie wave length of an ejected electron? the work function for potassium, k metal is 3.67x10" j. (hint: which transitions in the h atom, starting from 1-5, produce a photon of sufficient energy to cause an electron to be ejected from the surface of potassium metal?
