HD Animation: Snellius Law of Refraction

The interactive animation represents the geometric relationships that exist for a refracted beam of light (Snellius’ law of refraction).

Note on use

Description of the animation

To change the angle of incidence of the light beam, click on the top of the beam and move the mouse to the left or right.

Alternatively, you can change the target area of the light beam. To accomplish this, move the marker at the bottom of the animation.

In addition to a straight surface, curved and wave-shaped surfaces can also be displayed. The shape of the surface can be changed using the points on the left and right sides.

The refractive index of the medium can be set between 1 and 10. The maximum refractive index observed in a naturally occurring material is 2.42. This value belongs to a mineral called zirconium oxide (also known as zirconia). Materials produced in laboratories can achieve higher refractive indices. Experiments have produced artificial materials with refractive indices of over 4. Such high-performance materials are often developed for specialised applications such as optical lenses, lasers and other optical devices.

Instructional idea

The scene shown can be partially reproduced with an experimental set-up. The advantage of the animation is that the geometric relationships can be quickly clarified when repeating the material.
