What do we call the theory of electromagnetism on the particle scale?
gravity electrodynamics
iron electrodynamics
light electrodynamics
quantum electrodynamics
33.2 The Four Basic Forces • The four basic forces and their carrier particles are summarized in the Table 33.1. • Feynman diagrams are graphs of time versus position and are highly useful pictorial representations of particle processes. • The theory of electromagnetism on the particle scale is called quantum electrodynamics (QED).
