A gas of hydrogen like ions is prepared in a particular excited state A. It emits photons having wavelength equal to the wavelength of the first line of the Lyman series together with photons of five other wavelengths. Identify the gas and find the principal quantum number of the state A.
The gas emits total of 6 wavelengths. Thus,

Thus the gas is in the 4^th state. Since the gas is hydrogen like ion and in the 4^th excited state, thus the gas is .
