The Balmer series for the hydrogen atom corresponding to electronic transition that terminate in the state of quantum number `n = 2`. Find the longest-wavelength photons emitted and determine its enegry.Strategy: The longest-wavelength photon is associated with the smallest enegry difference. Its emission in the Balmer series results from the transition form `n_(i) = 3`to `n_(f) = 2`.
