Questions and Answers

What is the primary consequence of the coherent scattering process described in the text?

  • The incident photon is scattered with no loss of energy. (correct)
  • The incident photon causes the atom to undergo ionization.
  • The incident photon is scattered with significant loss of energy.
  • The incident photon causes the electron to be ejected from the atom.

    • What is the primary reason that coherent scattering is of little significance in most diagnostic procedures?

  • The scattered radiation does not leave the beam. (correct)
  • The scattered radiation has a high energy that can damage the material.
  • The scattered radiation leaves the beam.
  • The scattered radiation produces ionization in the material.

    • Which of the following properties of the incident photon is most important for the coherent scattering process to occur?
