An imaginary atom has just three energy levels 0 eV, 1 eV, and 3 eV. Draw an energy level diagram for this atom, and show all possible transitions between these energy levels. For each transition, determine the photon energy and the photon wavelength. Which transitions involve the emission or absorption of visible light?
