### Photoelectric Effect (Planck's Constant) Summary

#### Data & Results

The notebook entry for this lab is located here. We generated two Excel files for this lab as well: Planck.xlsx and First Order.xlsx.

We measured two different things in this lab related to the photoelectric effect, but only one of these has an accepted value - Planck's Constant. This value is

We came up with many different value for Planck's constant. We obtained two from the first order maxima from the light source, each being a separate run through the colors:
