Let's use the Bohr model equations to explore some properties ofthe hydrogen atom. We will determine the kinetic, potential, andtotal energies of the hydrogen atom in the n=2 state, andfind the wavelength of the photon emitted in the transitionn=2?n=1.
Find the wavelength for the transition n=5 ?n=4 for singly ionized helium, which has one electron anda nuclear charge of 2e. (Note that the value of theRydberg constant is four times as great as for hydrogen because itis proportional to the square of the product of the nuclear chargeand the electron charge.)
Express your answer in nanometers to three significantfigures.
