Description

This lecture discusses the setup of two polarizers with a half-wave plate in between, analyzing the change in intensity and polarization direction of light passing through them. By understanding the principles of circular and linear polarization, the instructor explains how the light intensity is preserved after passing through the second polarizer, resulting in a ratio of half between the intensity leaving the second polarizer and that entering the first one.
