Tiny particles are affected in different ways than we are by waves. There are several different effects that must be discussed.

Albert Einstein revolutionized the world of physics when he discovered the special theory of relativity. It is only possible due to his contributions that valuable technologies like GPS function. But what is it exactly?

Mirrors can interact with light in interesting ways. In fact, reflection and refraction are probably most people's engagement with laws of physics surrounding light in their daily life.

We have discussed electric fields and magnetic fields, and the way that they change and interact. The full interaction of these fields will create electromagnetic waves, the study of which will consume the rest of these notes.

The final piece to the puzzle of electromagnetism here is electromagnetic induction, where we use magnets to create current.

The question of how magnets work has long puzzled many. We will endeavor to answer all of those questions today.

Circuits are the method by which all electricity travels throughout the world and power every single device in existence. It is therefore crucial to understand them while understanding electricity.

Besides electrical charge and field, there's another force that is relevant to electricity: electric potential.

What is electricity, and how does it work?
