Based on hydrogen emission lines (l's) measured in the laboratory, a student plots (1/lambda) vs. (1/n(initial)^2) from which she obtains the following equation: (nm = nanometers) (1/lambda) = [(-0.010968nm^-1)/n(initial)^2] + 0.0012189nm^-1
a) Based on this equation, what is the value of the Rydberg constant (R) in m^-1? (5 significant figures)
b) What is nf?
