Energy and Wavelength of a photon in pair production

Click For Summary
SUMMARY

The discussion centers on the energy and wavelength of photons involved in pair production, specifically addressing a scenario where an electron and positron each possess a kinetic energy of 220 keV. The calculated energy for the photon required for pair production is 1.46 MeV, which corresponds to a wavelength of 8.49 x 10-13 m. The participants explore the implications of these values in the context of particle-antiparticle collisions.

PREREQUISITES
  • Understanding of pair production in particle physics
  • Knowledge of energy-mass equivalence (E=mc2)
  • Familiarity with photon energy calculations (E=hf)
  • Basic concepts of kinetic energy in relativistic contexts
NEXT STEPS
  • Research the principles of pair production in quantum mechanics
  • Learn about the relationship between energy and wavelength of photons
  • Study the conservation of energy and momentum in particle collisions
  • Explore advanced topics in particle-antiparticle interactions
USEFUL FOR

Students and educators in physics, particularly those focusing on quantum mechanics, particle physics, and energy interactions in high-energy environments.

Homework Statement



Electron and positron each have a kinetic energy of 220 keV even when far apart.

Homework Equations





The Attempt at a Solution


I have no idea. My book says the answer 1.46 MeV, 8.49 x 10^-13 m but I don't know how to get that.

Position is antiparticle of electron. So what will happen when they collide?
