A photon is emitted, when an electron makes a transition from a higher energy level to a lower energy level. If the energy of the higher energy level is 2.6891020J and the energy level of the lover energy level is 5.4451019J, what is the wavelength of the emitted photon (in nm )? Report your answer to one decimal place, and do not include the unit (nm) in your
