SUMMARY

The discussion focuses on the effect of multiple polaroid filters on light transmission percentages, specifically when vertically polarized light passes through three filters oriented at 30, 60, and 30 degrees to the vertical. The key takeaway is the need to apply Malus's Law, which states that the transmitted intensity through a polarizer is proportional to the cosine square of the angle between the light's polarization direction and the polarizer's axis. The sequential nature of the filters requires careful calculation of the output intensity from one filter as the input for the next.

PREREQUISITES
  • Understanding of Malus's Law in optics
  • Knowledge of light polarization concepts
  • Familiarity with the relationship between angle and intensity in polarizers
  • Basic principles of the Lyman series in atomic physics
NEXT STEPS
  • Study Malus's Law and its applications in optics
  • Explore the concept of light polarization and its practical implications
  • Research the Lyman series and its significance in hydrogen spectroscopy
  • Investigate the effects of multiple polarizers on light transmission
USEFUL FOR

Physics students, optical engineers, and anyone interested in the principles of light behavior through polarizing filters.

Plz help me For these physics problems!

Plz help me For these physics problems! Plz give me the solutions. Thank you.

1. Vertically polarized light is passed through three successive polaroid filters. The transmission axes are at 30, 60, and 30 degrees to the vertical. What percentage of the light gets through?

2. What value of n is associated with the lyman series line in hydrogen with lamda = 96 nm? Could it be any other series? Explain?

Annie, no one is going to "give" you the solutions. I'll give you a hint for #1 though.

1) Look for a relationship between light intensity and polarizer angle. Then realize that the output intensity from one polarizer is the input intensity for the next polarizer in sequence (but be careful with the angle on the successive polarizers).
