Rydberg s constant

Bohr was able to express Rydberg s constant in terms of the electron s mass, nte, the electron s charge, e, Planck s constant, h, and... 

Alilfikan s oil-drop experiment settled the argument and determined accurately (within one part in a thousand) both the charge and, by virtue of the charge-to-mass ratio, the mass of the electron. Both numbers allowed the Danish physicist Niels Bohr to finally calculate Rydberg s constant and provided the first and most important proof of the new atomic theory. 

Strategy We are given the initial and final states in the emission process. We can calculate the energy of the emitted photon using Equation (7.6). Then from Equations (7.2) and (7.1) we can solve for the wavelength of the photon. The value of Rydberg s constant is given in the text.
