This following applet is illustrate refraction with dog running

Original project illustrate refraction with dog running

The velocity of wave changes when wave move from one media into another media.
For light: The index of refraction is defined as $n=c/v$, where c is the speed of light in vacuum, and v is the speed of light in media.

The following animation use many dogs running from one region into another region.
Due to the condition on the ground , dogy's speed is different when running from one region into another region.
It obeys Snell's Law $n_1 \sin\theta_1 =n_2 \sin\theta_2$.

You can use $n_1,n_2$ slider to change speed of running dogs and c1 to change it moving direction.
