Problem

A simplified atomic spectrum shows two emission lines. One line corresponds to a

1.89\,\text{eV}

photon emitted when the atom drops from level 2 to level 1. The other corresponds to a

0.97\,\text{eV}

photon emitted when the atom drops from level 3 to level 2. What is the energy of level 3 relative to level 1? a)

1.89\,\text{eV}

0.92\,\text{eV}

2.86\,\text{eV}

2.50\,\text{eV}
