la) Calculate the photon energy associated with a transition from the n = 2 level to the n = 6 level in a He+ ion. Note: Mathematically, values of the quantum number n are considered to have infinite sig figs. b) Is a photon being absorbed or emitted in this transition? c) Without any calculation, would you expect the photon energy to be larger or smaller for the transition from the n = 1 level to then = 6 level?
