This animation illustrates Snell’s law of refraction at a curved interface between two optical media. An interactively positionable light ray strikes the surface and is both reflected and refracted, depending on the adjustable refractive index of the second medium. The angular relationships between the incident, reflected, and refracted rays are visualized through dynamic angle markers.… Read More »

The interactive animation shows how a light beam is reflected and refracted on a semi-transparent surface (Snell’s law of refraction). Note on 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 »
