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?

Low frequency of the photon.

Low energy of the photon. (correct)

High energy of the photon.
