  1. 4. Light strikes a metal can cause the emission of an electron.
  2. 5. The X-ray spectrum emitted by the anode consists of _______ and a continuous spectrum of radiation.
  3. 6. The maximum wavelength above which no leakage current or photoemission occur since the photon energy is now less than the gap between the valence and the conduction band.
  4. 8. The minimum quantity of energy which is required to remove an electron from the surface of a metal to infinity.
  5. 9. Dependent or independent? The kinetic energy of photoelectrons and the intensity of incident radiation.
  6. 11. a continuous spectrum of X-ray radiation caused by the violent deceleration of charges of the electrons as they hit the anode.
  7. 12. ___________ of an ejected electron equals the photon energy minus the binding energy BE of the electron in the specific material.
