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.

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
