Description

This lecture explores the use of glasses in 3D movies, focusing on the phenomenon observed when wearing glasses with different polarizers for each eye. By analyzing the orientation of the polarizers and the angles involved, the instructor explains how the observed darkening of the neighbor's eye occurs. The solution to the exercise involves understanding the relationship between the angles of the polarizers. Additionally, the lecture delves into the practical application of 3D glasses in cinemas, highlighting the combination of quarter wave plates and linear polarizers to filter light. The instructor demonstrates how these glasses allow viewers to freely move their heads while maintaining the 3D effect, and discusses the wavelength dependency of the polarizers, showcasing experiments that reveal color absorption variations.
