Given that the energies of the ground and excited states of the Hydrogen atom may be calculated using E=(-13.6eV)/n2 and that Planck’s constant is h=6.626 x 10-24 J∙s and 1eV=1.602 x 10-19 J, find the wavelength of the x-ray emitted when a Hydrogen atom initially in the n=4 excited state decays to the ground state.
