SUMMARY

The discussion centers on the phenomenon of TM (transverse magnetic) polarization and its relationship with Brewster's angle. When the angle of incidence is less than Brewster's angle, the reflected light undergoes a π phase shift. This behavior is explained through the complex reflection coefficient, denoted as ##r_p##, particularly in scenarios of internal reflection where the refractive index of the second medium (##n_2##) is less than that of the first medium (##n_1##).

PREREQUISITES
  • Understanding of TM polarization in optics
  • Familiarity with Brewster's angle and its significance
  • Knowledge of complex reflection coefficients
  • Basic principles of internal reflection and refractive indices
NEXT STEPS
  • Study the derivation of the complex reflection coefficient for TM polarization
  • Explore the mathematical implications of Brewster's angle in optical systems
  • Investigate the effects of internal reflection on light behavior
  • Learn about phase shifts in wave optics and their applications
USEFUL FOR

Students and professionals in optics, physicists studying wave behavior, and engineers working with optical systems will benefit from this discussion.

Sorry
i have question for TM polarization.
i don't understand why if the angle < brewster's angle,then the reflected light will experience an pi phase shift?
can anybody explain why?

Take a look at these equations, especially ##r_p## which is the (complex) reflection coefficient for TM polarization. In particular, you will be interested in the so-called internal reflection, that is when ##n_2 < n_1##.
