(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the Bohr model of the hydrogen atom, if the electron is in the second orbit with a radius of 2.12 Å. What is the de Broglie wavelength of the electron?

2. Relevant equations

λ = 4h^2ε/me^2

3. The attempt at a solution

I found this equation hunting around online and figured out that the constant is 2 times the energy level, but I do not have all of this information. How would I solve this problem?
