Which of the following describes the process of pair production?.
- A.A photon creates a particle-antiparticle pair.
- B.A particle decays into a photon and another particle.
- C.Two particles collide and produce a photon.
- D.A particle absorbs a photon.
Model answer
What a good answer should say
- A photon creates a particle-antiparticle pair.
Explanation
Why this works
Pair production is the process where a photon with sufficient energy interacts with a field (like a nucleus) to create a particle-antiparticle pair, demonstrating the conversion of energy into mass.
