3) The frequency of one of the lines in the Paschen series of the spectrum of atomic hydrogen is 2.74 x 104 Hz. Identify the principal quantum number of the upper state in the transition 4) One of the lines in the spectrum of atomic hydrogen occurs at 397 nm. At what wavelength does it occur in He' (if we disregard the mass differences)?
