IB Physics SL E.1.4 Atomic Transitions

Practise reading atomic energy-level diagrams, assigning absorption or emission and calculating the photon frequency or wavelength corresponding to a permitted transition.

Exam points

calculate |Efinal - Einitial| for the two stated levels before converting the energy units
identify upward transitions as photon absorption and downward transitions as photon emission
match discrete transition energies to absorption or emission lines rather than a continuous spectrum

This question is about energy level transitions.

Some of the electron energy levels for a hydrogen atom are shown.

Figure for Question E.1.4—Atomic transitions question 1 — IB Physics SL

A hydrogen atom is excited to the -1.51 eV level.

On the diagram, label using arrows all the possible transitions that might occur as the hydrogen atom returns to the ground state.

only the three correct arrows on diagram;

(-1.51 \text { to }-3.40,-1.15 \text { to }-13.6 \text { and }-3.40 \text { to }-13.6)
