In the context of photoemission as depicted in Fig., how is momentum conservation reconciled, considering that light (photons) has momentum in a different direction from the emitted electrons?
Options
- AThe momentum is conserved only in the macroscopic system, with no transfer to the metal at the microscopic level.
- BMomentum is directly transferred to the emitted electrons, enabling their release from the metal surface.
- CConservation of momentum accounts for the transfer of momentum to both the nucleus and electrons, resulting in the emission of excited electrons.
- DThe momentum is primarily transferred to the surrounding environment, allowing the emitted electrons to gain sufficient energy for release.
Correct answer
C. Conservation of momentum accounts for the transfer of momentum to both the nucleus and electrons, resulting in the emission of excited electrons.
Step-by-step solution
Correct Option is : (C)
Conservation of momentum accounts for the transfer of momentum to both the nucleus and electrons, resulting in the emission of excited electrons.
Conservation of momentum accounts for the transfer of momentum to both the nucleus and electrons, resulting in the emission of excited electrons.
