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 mathematical formulation?A set of four coupled partial differential equations
2. What is the discoverer?James Clerk Maxwell (early form), Oliver Heaviside (modern formulation)
3. Why did Maxwell add the displacement current term?He added it to fix a mistake in Ampère's law and to show that changing electric fields can create magnetic fields. This change helped predict that light is an electromagnetic wave. It made the equations complete.
4. How do Maxwell's equations explain light?They show that light travels as waves made of electric and magnetic fields that move together. The equations predict the speed of these waves, called 'c', which is the same speed for all light. This idea helped scientists understand that light is a type of electromagnetic radiation.

Partial Differential Equations: Equations involving unknown functions of multiple variables and their partial derivatives.
Electromagnetic Radiation: Energy that travels and spreads out as it goes; includes radio waves, visible light, and X-rays.
Electric Charge: A fundamental property of matter that causes it to experience a force when placed in an electric or magnetic field.
Electric Current: The flow of electric charge, typically through a conductor.
