Brackett series of lines are produced when electrons excited to high energy levels make transitions to the n = 4 level. (a) Determine the longest wavelength in this series. (b) Determine the wavelength that corresponds to the transition from The first excitation potential of a hypothetical hydrogen-like atom is 15 V. Find the third excitation potential of the atom.
