← ScienceWhich outcome occurs when an electron exceeds escape velocity?
A)Photoelectric emission releases the electron✓
B)Pair production generates antimatter particles
C)Compton scattering shifts photon wavelength
D)Quantum tunneling increases electron probability
💡 Explanation
Photoelectric emission releases the electron because photons transfer sufficient energy for the electron to overcome the material's work function via excitation energy; therefore, it is ejected rather than undergoing pair production or Compton scattering, which involves high-energy photons.
