The observed lines in the hydrogen spectrum all arise from jumps of electrons from one energy level to another. The wavelengths in nanometers corresponding to these transitions can be calculated from equation 4 where AE is the difference in energy in kJ/mole between any two allowed energy levels. Fill in the table below for the listed transitions: AE (= Enhi - Ento) 2 (nm) (see eq. 4). Transition (nhiNlo) 2 1 3 1 3 2 41 4- 2 4- 3 5 1 5 2 5- 3 5 4 6 2 6. 3 6. 4 6.
