Problem

An electron in a hydrogen atom is excited to the fourth Bohr orbit (

n=4

). It returns to the ground state (

n=1

) in two successive steps. One of the emitted photons has a wavelength of

486.1\,\text{nm}

. Determine the wavelength of the other photon. (Use

R_{H}=1.097\times10^{7}\,\text{m}^{-1}
