Quantum electrodynamics (QED) is a fancy way of describing how light and tiny particles called electrons and photons interact with each other. Imagine you have a bunch of marbles (electrons) and a bunch of balls (photons) bouncing around.
In quantum electrodynamics, we study how these marbles and balls play together. Sometimes, the marbles can absorb the balls, and other times they can release the balls they have absorbed. This interaction happens in a very special way, following certain rules that scientists have discovered.
QED helps us understand why some things are transparent, like glass, and why some things reflect light, like mirrors. It also explains how we can see colors and how electricity and magnetism work.
So, quantum electrodynamics is like a big game between marbles (electrons) and balls (photons) where they exchange energy and make cool things happen in the world around us.
