Chem 1045 Line Spectra 2 of 7 The energy emitted or absorbed appears as some sort of radiation with a characteristic wavelength: Since the electron can only exist in certain main energy levels, the transitions between energy levels only involve certain energies and only certain wavelengths of radiation are emitted (or absorbed). The wavelengths absorbed or emitted make up a _________________________________ The wavelength emitted or absorbed during an electron transition can be calculated: -1 22 12 11 1 = 0.0109737 nm - nn ⎛⎞ ⎜⎟ λ ⎝⎠
