In the American Journal of Physics, Aaron Slepkov from Trent University explores the physics of how polarization-filtered colors emerge, how they can be controlled, and why subtle changes in viewing angle, sample orientation, and the order of layers of films between polarizers can have dramatic effects on the observed colors. The research emphasizes visual examples of concepts related to birefringence, such as addition, subtraction, and order-of-operations.
