A gas of hydrogen-like ion is prepared in such a way that the ions are only in the ground state and the first excited state. A monochromatic light of wavelength 1216 A is absorbed by the ions. The ions are lifted to higher excited states and emit An electron in a hydrogen-like atom is in an excited state. It has a total energy of -3.4 eV. Calculate (a) the kinetic energy and (b) the de-Broglie wavelength of the electron.
