You measure the emission spectrum of an atom that you suspect to be hydrogen. you have no absolute calibration of the wavelength, but the ratios of the first 3 wavelengths in the series that you measure are 1 : 0.741 : 0.661. which series is this (e. g. lyman, balmer, paschen, brackett)? justify your answer.
