The He+ ion contains only one electron and is therefore a hydrogen-like ion. Calculate the wavelengths of the first four transitions in the Balmer series of the He+ ion. List your answers in increasing transition order by entering the wavelength that corresponds to the first transition on the left. (The Rydberg constant for He is 4.39 × 107 m−1 and the Rydberg constant for H is 1.097 × 107 m−1)


Calculate these wavelengths for the same transitions in an H atom.
