Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the governing equations?Maxwell's equations provide a complete classical description of electromagnetic fields
2. What is the mediating particle?In quantum electrodynamics, the photon is the quantum of the electromagnetic field
3. How does electromagnetism make lights work?Electricity moves through wires, creating electric and magnetic fields. These fields produce light in bulbs and LEDs. The light we see is actually an electromagnetic wave.
4. Who proved that light is an electromagnetic wave?James Clerk Maxwell wrote equations that showed light is a wave made of electric and magnetic fields. His work in the 1860s predicted this and was later confirmed by experiments.

Electromagnetic Radiation: Energy that travels and spreads out as it goes, including visible light, radio waves, and X-rays.
Quantum Electrodynamics (QED): A quantum field theory that describes how light and matter interact.
Photon: The fundamental particle of light and electromagnetic radiation, carrying energy and momentum.
