Three of the known wavelengths of the emission spectrum for helium are 402.6 nm, 447.1 nm, and 587.5 nm.   If n1 = 2 for these lines, calculate n2 using the Rydberg equation.  Use the correct number of significant figures and be sure to convert nm to m for this calculation. Explain why your results of these calculations indicate that the electron behavior of atoms of elements with more than one electron is not well described by the Rydberg equation if the Bohr model of the atom is correct.
