Solve the given problems:
Problem A: In the Bohr model of the hydrogen atom, what is the de Broglie wavelength for the electron when it is in the n = 2 level?
Problem B: In the Bohr model of the hydrogen atom, what is the de Broglie wavelength for the electron when it is in the m = 5 level?
Problem C: Compare the de Broglie wavelength to the circumference 2?r2 of the orbit in part A.
Problem D: Compare the de Broglie wavelength to the circumference 2?r5 of the orbit in part B.
Please clarify the equations and steps are used to get the answer. Thanks!
