Understanding Electro-Magnetic Waves in Matter: Reflection, Refraction & Applications

Explore the interaction of electro-magnetic waves in linear media, focusing on velocity changes in materials, reflection, transmission, refraction, and boundary conditions. Delve into normal and oblique incidences, Snell's Law, reflection and transmission coefficients, total internal reflection, Fresnel's Laws, Brewster's angle, polarization phenomena, and applications like binoculars, jewelry, fiber optics, and near-field optical scanning microscopes. Discover how materials under stress affect polarization, and more. For in-depth insights, visit canon.com/technology/s_labo/light/003/03.html.
