5. The energy levels for a quantum mechanical system as given: Es = 8eV, E4 = 7eV, E3 = 5eV, E2 = 2eV, E1 = 0 All electrons are in ground states. Radiation containing all wavelengths corresponding to the photon energies betweenl to 10 e V is passed through the gas. Which of the incident photons will be absorbed by the gas? (AE must be equal to one of the transisyoons given to be absorbed.) Es-E4 Es-E3 Es-E2 = Es-E1 = E4-E3 E4-E2 = E4-E1 E3-E2 E3-E1 E2-E1
