In the Bohr model, what happens when an electron makes a transition between orbits?

Two of the emission wavelengths in the hydrogen emission spectrum are \(656 \mathrm{~nm}\) and \(486 \mathrm{~nm}\). One of these is due to the \(n=4\) to \(n=2\) transition, and the other is due to the \(n=3\) to \(n=2\) transition. Which wavelength corresponds to which transition?

Sketch the \(3 d\) orbitals. How do the \(4 d\) orbitals differ from the \(3 d\) orbitals?
