With all the information from the methods section, we can now look at our data.

For method 1, we have graphed the data of all the different voltage measurements, from the photodiode, verses the polarizer angle. Ideally, we wanted to start these measurements at \(\frac{\pi}{4}\), so we took some preliminary measurements to find the angle at which the sensitivity reaches its maximum. At 340 degrees, we had a voltage output of 0.2078V, which seemed to be the highest the voltage could reach.

Based on Eq. \ref{eq:Diode_Response}, we were able to confirm a cosine squared function.
