Animation: Snellius Law of Refraction

The interactive animation depicts the relation between angle of incidence and angle of refraction when a light beam is passing through a transparent material (Snellius Refraction Law).

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 straight surfaces, curved and wavy surfaces can also be represented. Using the markers on the left and right side, the shape of the surface can be altered.

The materials refractive index can be set between 1 and 10. The high values >3 occur in reality only with very few materials.

If you click in the large rectangle of the animation, formulas are displayed.
