1. The problem statement, all variables and given/known data Compare the deBroglie wavelength for an electron in the n=6 orbit of He+ compared to the n=2 orbit. Is the deBroglie wavelength the same, smaller, or larger? Derive this. 2. Relevant equations Quantization of Paths of Electrons: 2 pi r = n (lambda) Bohr Radius: rn=n2 aB 3. The attempt at a solution So plugging eqn 2 into eqn 1 and solving for lambda (and using Z = 2 for He+) gives: wavelength = pi n aB So using this, the deBroglie wavelength of n=6 would be 3 times larger than the n=2 wavelength? I really don't know if this is correct. I don't know if the Bohr model can be used with deBroglie (they are kind of related right?) Edit: Ok the math symbol stuff is kind of messed up, I fixed what I could but it kept showing things wrong.
