Meaning
A Feynman diagram is a type of graph used to represent the interactions between subatomic particles.
About Feynman Diagrams
- Feynman diagrams have time on the y-axis and space on the z-axis.
- Feynman diagrams are used to simplify complex equations used to represent subatomic particle interactions.
Examples
 |
 |
| This Feynman diagram shows the electromagnetic interaction between two protons via the virtual photon. | This Feynman diagram shows the weak interaction in which a neutron decays into a proton.
