(a) Calculate the frequency of revolution and the orbit radius of the electron in the Bohr model of hydrogen for n 100, 1000, and 10,000. (b) Calculate the pho- ton frequency for transitions from the n to n 1 states for the same values of n as in part (a) and compare with the revolution frequencies found in part (a). (c) Explain how your results verify the correspondence principle.
