How Does the Angle Between Two Polarizing Sheets Affect Light Intensity?

Click For Summary
SUMMARY

The discussion focuses on the effect of the angle between two polarizing sheets on the intensity of transmitted light. When unpolarized light passes through two polarizing sheets, each sheet reduces the intensity by 50%. To achieve a transmitted light intensity of one-third of the incident light, the angle between the polarizing sheets must be calculated using Malus's Law. This law states that the transmitted intensity is proportional to the cosine square of the angle between the light's polarization direction and the axis of the polarizer.

PREREQUISITES
  • Understanding of unpolarized and polarized light

Polarization physcs sum?

Unpolarized light is incident on 2 polarizng sheets placed on top of the other...each sheet reduces the intensity of unpolarized light by 50%..wat must be the angle between the characteristic direction of sheet such tat the intnsty of transmittd light is 1/3rd of the incident?
