For this question consider the figure to the right that shows an energy level diagram for a certain atom (not hydrogen). Several transitions are shown and labeled by letters. Note the diagram is not drawn to scale.
(A) Which transition corresponds to the emission of the photon with the longest wavelength?
(B) Which transition corresponds to the emission of the photon with the shortest wavelength?
(C) Which transition corresponds to the emission of the photon with 177 nm wavelength?
(D) Which transition corresponds to the emission of the photon with 124 nm wavelength?
