Answer:
  1. Energy levels of atom and energy of photons are quantized 
  2. Since the photon from the laser has energy greater than the ground state (E0) energy there will be a transition of an atom from the ground to an excited state.
  3. Energy of photon from laser is 1.5k so it cannot attain the first excited state (E1) as well as second excited state (E2)
  4. It will release the extra 0.5k energy as a photon or other form of energy and will attain the first excited state (E1)
  5. Further, the atom can again return to the ground state (E0) by releasing a photon
