Hydrogen atom absorbs radiations of wavelength `lambda_0` and consequently emit radiations of 6 different wavelengths, of which two wavelengths are longer than `lambda_0`. Chosses the correct alternative(s).

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.
