Confused on Electron Double slit experment

Click For Summary
SUMMARY

The discussion centers on the confusion surrounding the double-slit experiment with electrons, as presented in Brian Greene's book "The Elegant Universe." A participant expresses difficulty in understanding how electrons, despite being particles, exhibit wave-like behavior and create interference patterns. Recommendations include halting the reading of popular science books in favor of foundational quantum mechanics textbooks, with specific emphasis on Richard Feynman's works and the concept of wave-particle duality as articulated by the de Broglie hypothesis.

PREREQUISITES
  • Basic understanding of wave phenomena, specifically interference.
  • Familiarity with the concept of wave-particle duality.
  • Knowledge of the de Broglie hypothesis regarding particle wavelengths.
  • Exposure to introductory quantum mechanics principles.
NEXT STEPS
  • Read Richard Feynman's books on quantum mechanics for clearer insights.
  • Study introductory quantum mechanics textbooks for foundational knowledge.
  • Research the concept of interference in wave phenomena.
  • Explore educational videos on quantum mechanics, particularly Feynman's lectures on YouTube.
USEFUL FOR

Students, educators, and anyone interested in understanding quantum mechanics, particularly the double-slit experiment and wave-particle duality of electrons.

Hello. Just to set things straight this is my first post here and I am also a complete nube when it comes to things this confusing. I started reading a book called "the elegant universe" by Brian Greene. So far I think the book is great but I am stumped on one part of the book. Its the part when he starts talking about the double slit experment with electrons. I understand that with photons but I get confused when he starts talking about electrons. On how even if you shoot one by one you still get an interference pattern. I am a 10th grade student so I am not taught this in school yet but from what I read there are some preety smart people here. I was just woundering if anyone could give me some links(because i don't think anyone wants to tell me exactly how electrons make an interference pattern)on explaining this stuff. I have tried lots of different websites and their all to hard for me to understand. any help would be great. I just feel like I can't go on in the book until I understand how electrons make a pattern like the way they do on that photopaper stuff. All I know is that they are a particle and a wave but after that I am dead lost.:confused:

Welcome to Physics Forums and to the "crazy" world of quantum mechanics. My advise for you is to stop reading this book right now. You can read popular science books for entertainment, but they will produce more questions, confusion, and frustration, than truly enlightening answers.

I would recommend you to find a basic textbook on quantum mechanics and start to study it systematically. It is even better to find a few textbooks and read them in parallel. Quantum mechanics is a difficult subject, and I cannot think of a single textbook that explains it clearly. Moreover, people still keep arguing what quantum mechanics is about. So, looking at it from different points of view is definitely a plus.

The best place to look for explanation of the double-slit experiment is in Feynman's books. There are also fascinating videos of his lectures on YouTube.

Eugene.

dear,
first of all u have to know about the interference.This is a wave phenomenon.First read about it from google then u will understand better.
Now,after u read intefernce,the de broglie hypothesis says that all particles have wave phenomenon and their wavelength is by \=h/p.so electrons are waves and once they r waves they ought to show the wave phenomenon that is interference and a lot more.
