SUMMARY

The relationship between angle and polarization in modern optics is established through geometric principles and the behavior of light. Specifically, the discussion highlights how the angle of incidence at point A correlates with the angle of reflection. It emphasizes that to transition from linearly polarized light to circularly polarized light, one must calculate the necessary phase difference (Δ) without needing to solve for the angle itself, focusing instead on validating the equation with the given values.

PREREQUISITES
  • Understanding of geometric optics principles
  • Familiarity with polarization of light
  • Knowledge of phase difference calculations
  • Basic concepts of linear and circular polarization
NEXT STEPS
  • Research the mathematical derivation of phase differences in optics
  • Explore the principles of Brewster's angle in polarization
  • Learn about the applications of circular polarization in optical devices
  • Investigate the effects of angle of incidence on light reflection and transmission
USEFUL FOR

Optics students, physicists, and engineers working with optical systems who seek to deepen their understanding of light behavior and polarization effects.

Homework Statement
Problem 2.18 is what I want to know. I think I have to use equation (eq 2.72) about phase difference in TIR, but , I'm not sure because n=1.65 so it's complicate..

Which part is unclear?
From geometry you can relate the angle at A to the angle for the reflection. From the condition that linearly polarized light becomes circular polarized light you can calculate the phase difference ##\Delta## you need. You don't need to solve for the angle here luckily, you just need to show that the given value makes the equation correct.
