Day 20

In the morning meeting we reviewed some of our outlines for our presentations. Today I mainly worked on my presentation because the rest of the students working in the lab had their presentations at the end of this week. After creating most of the slides for my presentation I also made some more images. One of the images I created was a graph of the magnetic field versus the position the probe was on the barcode. I have also included a picture of the barcode and you can see how the peaks on the graph below correspond to the thickness of the black line on the barcode. The dips, or relative minimums, represent where the white lines are (where there is no black ink).
