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} + + Plot the expected dependence of the output intensity as a function of the angle $\theta$ between two polarizers, using Eq.(1). Estimate the number of points you need to take to reliably reproduce this curve in the experiment. + +\section*{2. Optimization of the measurement settings} +Examine Eq.(4) to find the value of the angle $\theta$ that will provide maximum useful signal for measuring $\phi$. + +\section*{3. Estimation of the expected Faraday rotation} +Using Eq.(2) roughly estimate the value of the expected rotation angle for $B\approx 10$~mT. Check on-line sources to find a reasonable value for $C_V$ for glass. + +\section*{4. Error analysis} +In this experiment you will be determining the error in the amplitude of an oscillating signal using its digitized form, recorded by an oscilloscope. A sample yellow trace, shown in Fig.(3), depicts the change in the signal voltage as a function of time. What would be a good measure of the uncertainty in its amplitude for such a measurement? + + + +\end{document} + |
