Optics

This animation shows Snell’s law at a curved interface. A light ray strikes the surface and is reflected and refracted. The refractive index is adjustable. The angular relationships between the incident, reflected, and refracted rays are visualized through dynamic angle markers. Links Animation Description The animation shows a light ray emitted from a flashlight striking… Read More: Law of Refraction »

The interactive animation shows how a light beam is reflected and refracted on a semi-transparent surface (Snell’s law of refraction). Instructions for Use As with all animations, the windows can be enlarged or reduced by clicking on them. After starting the application, you can view the animation in full-screen mode. To do this, click on… Read More: Reflection and Refraction »
