SJK Incomplete Feedback Notice
My feedback is incomplete on this page for two reasons. First, the value of the feedback to the students is low, given that the course is over. Second, I'm running out of time to finish grading!

Yes, the error does look high (and for summary it would have been good to put the values on this page to show the reader). Unfortunately, no time left to pour over your data to see if perhaps there's an error.
In general this lab was extremely fascinating, the physics behind calculating the diffraction of electrons passing through an extremely thin piece of graphite is pretty cool. Although my error was fairly high compared to the accepted value I feel I learned a lot and would love to repeat this experiment with the new bulb which I have learned just became available a couple weeks ago. Also, if I were to repeat this experiment, I think i would take a two measurements for each ring, one of the smallest diameter portion of the blurry ring and one of the largest diameter portion of the blurry ring too see how the values compared to the accepted value. An interesting part of these experiments is later on discovering what you could do differently and applying that thought process to the next experiment, thus improving your skills as an experimentalist.
