Emission and Absorption Lines - Rochester Institute of ... Absorption lines are based on the same physical principle as emission lines: they involve an atom jumping from one particular energy level to another. In this case, however, the jumps must be upwards, from a low level to a higher one. the hydrogen atom will absorb the photon and hop up to the n=2 level.
