High energy electrons and hydrogen(protons) A Level Physics Question

Click For Summary
SUMMARY

The forum discussion centers on a specific A Level Physics question regarding the diffraction of high-energy electrons and their interaction with hydrogen protons. The user seeks clarification on how the graph indicates electron diffraction and expresses uncertainty about the role of quarks in the experiment. The referenced question is from the January 2007 A Level Physics paper, specifically question 11b and 11c, which pertain to the experimental setup detailed on page 12.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly electron behavior.
  • Familiarity with particle physics, specifically quarks and their properties.
  • Knowledge of diffraction patterns and their significance in physics.
  • Ability to interpret experimental data and graphs in a physics context.
NEXT STEPS
  • Research the principles of electron diffraction and its applications in physics.
  • Study the structure of protons and the role of up and down quarks in particle physics.
  • Explore the experimental methods used to observe electron behavior in high-energy physics.
  • Learn about the significance of diffraction patterns in understanding wave-particle duality.
USEFUL FOR

Students preparing for A Level Physics exams, educators teaching particle physics concepts, and anyone interested in the experimental aspects of quantum mechanics.

Hi the question I am asking help for can be found here

http://www.hinchingbrookeschool.net/science/documents/A_GCE_Physics_B_2864_01_January_2007_Question_Paper.pdf

page 13. question 11b and 11c. Page 12 will give you the experiment setup

b - Can somehow please explain how that little widdle in the graph shows electrons are being defracted?

c - Not a clue. Guessing it's about up, down quarks but that's about it :\

Thanks :)
