Day 135: Finding Planck's Constant

We tried to find Planck's constant using LEDs. We got numbers in the ballpark, but they weren't great. I think I've learned how to make it work better next time. 

It's very interesting to see groups work through variables and units for their equations. We still like using J and E interchangeably for energy. We still aren't exactly sure how to find the units of the slope. These are skills I must emphasize more next year. 

Then we started talking about how much like particle photons really are? Like, do they have momentum? And, if they do, then do other particles, like the electron, have any wave properties?
