09.29: The diagram to the right shows the lowest four energy levels for an
e 1n+(f*vwn c n(l)94 kbvyiiyelectron in a hypothetical atom. The electron is excited to the -1 eV level of the atom and transitions to the lowest energy state by emitting only two photons. Which of the following energies could not belong to either of the
vyiky*(9v n (n+lenb1)ifw4cphotons?
