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

You can use the lab report template to prepare the submission of the pre-lab exercises. Feel free to use calculations or graphs in your final report, but you don't need to include prelab with the 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 $\Delta \sin(\theta)$ from the instrumental uncertainty the arc measurements $\Delta s$?
