Antiparticles and Photons

HideShow resource information
Pair production only happens when...?
It only happens when there is enough energy to produce the masses of the particles.
1 of 5
What is the definition of rest energy?
The amount of energy that would be produced if all of its mass was transformed into energy.
2 of 5
What are electron-positron pairs formed from?
A high energy photon.
3 of 5
Why are electron-positron pairs more commonly produced?
Because they have a relatively low mass. Low mass means low rest energy so less energy is needed for pair production to happen.
4 of 5
What happens when matter and antimatter annihilate?
All of the mass of the particle and the antiparticle gets converted back to energy as two gamma ray photons.
