1. Compare the Balmer series of hydrogen with the se- ries where n/ = 4 for the ionized helium atom He+. What is the difference between the wavelengths of the La and L/3 line of hydrogen and the nu = 6 and 8 of He+? Is there a wavelength of the Balmer series that is very similar to any wavelength values where n/ = 4 in He+? Explain.
2. Calculate the Rydberg constant for the single- electron (hydrogen-like) ions of helium, potassium, and uranium. Compare each of them with R and determine the percentage difference.
