Consider the following statements A and B and identify the correct choice in the given answers. A. Tightly bound electrons of target material scatter X -ray photon, resulting in the Compton effect. B. Photoelectric effect takes place with free electrons.

Options

  1. ABoth A and B are true
  2. BA is true but B is false
  3. CA is false but B is true
  4. DBoth A and B are false

Correct answer

D. Both A and B are false

Step-by-step solution

- Statement A: The Compton effect involves the scattering of X-ray photons by free or loosely bound electrons. Tightly bound electrons do not participate in Compton scattering; instead, they are associated with the photoelectric effect. Thus, A is false. - Statement B: The photoelectric effect requires electrons to be bound (especially tightly bound) to atoms, as the entire atom absorbs the recoil momentum. Free electrons cannot efficiently undergo the photoelectric effect. Thus, B is false. Both statements are inc
