A gas hydrogen like atoms can absorb radiations of `68eV`. Consequently, the atoms emit radiations of only three different wavelengths. All the wavelengths are equal or smaller than that of the absorbed photon. (`a`) Determine the initial state of the gas atoms. (`b`) Identify the gas atoms. (`c`) Find the minimum wavelength of the emitted radiation. (`d`) Find the ionization energy and the respective wavelength for the gas atoms.
