Thin Film Interference

This study guide covers thin film interference, focusing on transmission, reflection, and absorption of light. It explains phase changes during reflection (higher to lower index vs. lower to higher), and how these principles apply to constructive and destructive interference. The guide also explores real-world examples like soap bubbles and antireflective coatings, with an emphasis on how film thickness and wavelength affect interference patterns. Calculations are limited to normal incidence.
