Double slit experiment for AP physics

Click For Summary
SUMMARY

The discussion focuses on conducting the double slit experiment using both light and electrons for an AP Physics project. Participants are exploring methods to perform the electron variant, including the use of a single photon laser and DIY electron accelerators. A specific resource mentioned is an Instructables tutorial on building a cathode ray tube for electron acceleration. The group is seeking practical advice on executing these experiments effectively.

PREREQUISITES
  • Understanding of quantum mechanics principles related to wave-particle duality
  • Familiarity with laser technology, specifically single photon lasers
  • Basic knowledge of electron behavior and acceleration techniques
  • Experience with experimental design and safety protocols in physics experiments
NEXT STEPS
  • Research the principles of the double slit experiment in quantum mechanics
  • Investigate the availability and specifications of single photon lasers
  • Explore the Instructables tutorial on building a DIY electron accelerator
  • Study safety measures and protocols for handling electron guns and lasers
USEFUL FOR

High school physics students, educators in experimental physics, and hobbyists interested in quantum mechanics and optics experiments.

Hello,

I'm not sure if this is the right part of the forum to be posting this in (if it's not, feel free to move me), but I have a question about the double slit experiment.

For my AP Physics class, a group of seven other guys and myself are researching the double slit experiment, both with light and with electrons. Does anyone here have any advice on how a group of high schoolers would go about performing the experiment with electrons? (The light portion is easy, and our teacher is actually giving us access to a fairly large laser he has for another class).
 
Physics news on Phys.org
I'm currently doing one of these for a science fair, and during my research, I heard something about doing this with a single photon laser. I didn't know these existed (and I have yet to find one.) But if you can learn more about these, it might be interesting to look into.

It basically fired single photons overnight onto a film, then let the film develop, showing the interference pattern.

Not sure if you cared much about that, but anyways...
I also read something about cracking open a TV to get an electron "gun."

there's also a Electron accellerator tutorial on instructables, maybe you can modify that for your needs.
