Problem

A simplified energy-level diagram for an atom has the following energies (in eV): E4=0.0E_4 = 0.0, E3=−1.5E_3 = -1.5, E2=−3.0E_2 = -3.0, and E1=−5.0E_1 = -5.0. Which electronic transition would produce the photon with the shortest wavelength? (a) E4→E3E_4 \to E_3 (b) E3→E1E_3 \to E_1 (c) E4→E2E_4 \to E_2 (d) E1→E3E_1 \to E_3
