The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula: =E−Ryn2
In this equation Ry stands for the Rydberg energy, and n stands for the principal quantum number of the orbital that holds the electron.

Calculate the wavelength of the line in the emission line spectrum of hydrogen caused by the transition of the electron from an orbital with =n5 to an orbital with =n4. Round your answer to 3 significant digits.
