An element has three excited states relative to its ground state E0:
E1=2.10eV, E2=3.26eV, and E3=4.85eV. A spectral line at wavelength 590nm appears in its emission spectrum. (Use the conversion E(eV)=1240/λ(nm).) Which transition between the states most likely produced this line?
a) E3→E2
b) E0→E1
c) E1→E0
d) E3→E1
