We just learned about the Diode.

When you turn on a light bulb or use your flashlight, it makes things brighter.

But does light actually have parts?
Is it made up of little bits, or is it just light?

It turns out light is actually made up of something called photons.

Photons have no mass meaning they don't weigh anything like an atom does,
but they do move around and they are tiny little particles!
