Radiation Pressure: Exam Prep Questions & References

Click For Summary
SUMMARY

The discussion centers on key concepts related to radiation pressure, specifically the relationship between momentum and energy for photons, and the effects of reflection on radiation pressure. The equation p = E/c applies to both photons and waves, while the radiation pressure due to reflection involves more complex interactions than simple absorption. For further understanding of polarization, participants recommend consulting resources like Hyperphysics for comprehensive overviews.

PREREQUISITES
  • Understanding of photon momentum and energy relationships
  • Familiarity with the Poynting vector and its application in radiation pressure
  • Knowledge of wave-particle duality in physics
  • Basic concepts of polarization in electromagnetic waves
NEXT STEPS
  • Study the derivation of the Poynting vector in electromagnetic theory
  • Investigate the effects of reflection on radiation pressure in detail
  • Learn about the principles of polarization and its mathematical representation
  • Explore Hyperphysics for in-depth explanations of radiation pressure concepts
USEFUL FOR

Students preparing for physics exams, educators teaching electromagnetic theory, and anyone interested in the principles of radiation pressure and polarization.

Homework Statement



I have an exam on Monday and I'm trying to get a few concepts straight before then. I have a few questions...

1) p = E/c for a photon. Is this also true for a wave?
2) Assuming complete absorption, radiation pressure is 1/c x Poynting vector. What happens when there's reflection?
3) Anyone know a good reference for understanding how polarizes work? My notes aren't very good.

Thanks.

I am not 100% sure but I believe reflection is an absorption and re emission however I would consult with your professor because some tests and texts assume a photon bounces rather than becomes re emitted or phase shifted. Also Hyperphysics has some great overviews on the concepts ! I hope this helps!
