In the Balmer series of the hydrogen atom, an electron makes a transition from some higher state to the n = 2 shell. Suppose the initial state of the electron is n = 4.
(A) Calculate the energy of the emitted photon for this transition. ________eV
(B) Find the wavelength of the photon. To save time and effort, remember that a photon's wavelength is &lambda = hc/E = (1240 eV-nm)/E. _________ nm
