Question: An electron begins in the ( mathrm { n } = 5 ) orbital of a hydrogen atom. It then emits a

An electron begins in the \(\mathrm{n}=5\) orbital of a hydrogen atom. It then emits a photon of wavelength \(\lambda \) and falls to a lower energy level. Before it has a chance to change levels again, it absorbs a 10 eV photon and is ejected from the atom with a kinetic energy of 6.6 eV . What is the wavelength, \(\lambda \), of the first photon emitted?
An electron begins in the \ ( \ mathrm { n } = 5
