An electron in the hydrogen atom makes a transition from an energy state of principal quantum numbers ni to the n = 2 state. If the photon emitted has a wavelength of 434 nm, what is the value of ni? Can you give me the full solution? It says that the answer is 5 but I don't know how to get that. Thank you!
