Day 133: The Photon

What can we explain with light as a ray, as a wave, and as a particle? Let's whiteboard!

So which one is light, really?

Now I get to blow their minds. None of these models works perfectly. We have to make a kludgy wave-particle hybrid called a photon.

It ends in tears.

But then I made it all better when I said we can energy bar charts (LOL diagrams!) to explain the photoelectric effect. I'll show some whiteboards for that tomorrow.
