Calculate the wavelength of a photon emitted by a hydrogen atom when its bound electron undergoes a transition from state n = 6 to n= 2. Report your answer in nanometers (10-9 m) and provide 3 digits of precision (e.g. 567). Provide numeric values only; do not include units in your answer. The wavelength is nm.
