### 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

${\displaystyle h_{acc}=6.626\,068\,96(33)\times 10^{-34}~\mathrm {J} \cdot \mathrm {s} =4.135\,667\,33(10)\times 10^{-15}~\mathrm {eV} \cdot \mathrm {s} }$
