\chapter*{Electron Diffraction - Pre-lab exercise}

You can use the lab report template to prepare the submission of the pre-lab exercises. In fact, they will be a part of your final report.

\section*{1. Theoretical graph}

    Prepare a theoretical plot of Eq.(5) from the manual, using known values of the parameters and making reasonable guess on the range of the expected angles $\theta$.

\section*{2. Error propagation}
How you can find the uncertainty of $\sin(\theta)$ from the instrumental uncertainty of $s$? Discuss if the trigonometrical functions can be simplified.
