Question

Quizplus · Accepted Answer

The conservation of energy and momentum in particle physics allows a photon to produce an electron-positron pair only if there is another photon involved. This is because the initial photon must interact with a nucleus or another photon to satisfy these conservation laws, and the process of pair production (electron-positron creation) conserves charge, energy, and momentum with the involvement of another photon.
