Interference Patterns with Polarized Light

This lecture explains how to analyze interference patterns created by polarized light passing through a double-slit setup with a polarizer in one of the slits. By considering the light components parallel and perpendicular to the polarizer separately, and applying the formula for Young's double-slit experiment, the instructor demonstrates how to calculate the total intensity of light at the screen. The lecture concludes by showing that the total intensity of light, when the two components are added together, equals 5 times the intensity of the source, confirming the correct answer.
