  1. What’s the energy of a photon whose wavelength is 2.07 nm ?

  (A) 60 eV

  (B) 600 eV

  (C) 960 eV

  (D) 6,000 eV

  (E) 9,600 eV

  2. A metal whose work function is 6.0 eV is struck with light of frequency 7.2 x 1015 Hz. What is the maximum kinetic energy of photoelectrons ejected from the metal’s surface?

  (A) 7 eV

  (B) 13 eV

  (C) 19 eV

  (D) 24 eV

  (E) No photoelectrons will be produced.

  3. An atom with one electron has an ionization energy of 25 eV. How much energy will be released when the electron makes the transition from an excited energy level, where E= -16 eV, to the ground state?

  (A) 9eV

  (B) 11 eV

  (C) 16 eV

  (D) 25 eV

  (E) 41 eV

  4. The single electron in an atom has an energy of -40 eV when it’s in the ground state, and the first excited state for the electron is at -10 eV. What will happen to this electron if the atom is struck by a stream of photons, each of energy 15 eV ?

  (A) The electron will absorb the energy of one photon and become excited halfway to the first excited state, then quickly return to the ground state, without emitting a photon.

  (B) The electron will absorb the energy of one photon and become excited halfway to the first excited state, then quickly return to the ground state, emitting a 15 eV photon in the process.

  (C) The electron will absorb the energy of one photon and become excited halfway to the first excited state, then quickly absorb the energy of another photon to reach the fast excited state.

  (D) The electron will absorb two photons and be excited to the first excited state.

  (E) Nothing will happen

  5. What isthede Broglie wavelength of a proton whose linear momentum has a magnitude of 3.3 x 10-23 kg·m/s ?

  (A) 0.0002 nm

  (B) 0.002 nm

  (C) 0.02 nm

  (D) 0.2 nm

  (E) 2nm

  6. The difference between the mass of an intact phosphorus-31 nucleus and the sum of the masses of its individual protons and neutrons is 0.2825 u. What is the nuclear binding energy per nucleon?

  (A) 4.6 MeV/nucleon

  (B) 6.3 MeV/nucleon

  (C) 8.5 MeV/nucleon

  (D) 12.1 MeV/nucleon

  (E) 17.4 MeV/nucleon

  7. Compared to the parent nucleus, the daughter of a β-decay has

  (A) the same mass number but a greater atomic number

  (B) the same mass number but a smaller atomic number

  (C) a smaller mass number but the same atomic number

  (D) a greater mass number but the same atomic number

  (E) None of the above
