Consider the following statements A and B and identify the correct...
Consider the following statements and and identify the correct choice in the given answers.
A. Tightly bound electrons of target material scatter -ray photon, resulting in the Compton effect.
B. Photoelectric effect takes place with free electrons.
Options
- ABoth and are true
- B is true but is false
- C is false but is true
- DBoth and are false
Correct answer
D. Both and 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 incorrect.
