Consider the following statements A and B and identify the correct...

Statement A: "Tightly bound electrons of target material scatter X-ray photon, resulting in the Compton effect." This is false. The Compton effect involves the scattering of X-ray photons by free or loosely bound electrons. Tightly bound electrons are more likely to participate in the photoelectric effect, not Compton scattering. Statement B: "Photoelectric effect takes place with free electrons." This is false. The photoelectric effect primarily occurs with bound electrons (especially tightly bound ones), as the entire atom absorbs the recoil momentum, making the process more efficient. Free electrons cannot fully absorb the photon's momentum and energy, so the photoelectric effect is negligible for them. Conclusion: Both statements A and B are false. Correct choice: (4) Both A and B are false.
