This one also shows faint reflected wave (reflected off the interface). Refraction – Refracción http://www.youtube.com/watch?v=stdi6XJX6gU

For this video, you may wish to slide the bar through the 4 minutes+ video to see the ripple tank demonstration with Illustration of the law of refraction: Refraction 2.wmv http://www.youtube.com/watch?v=C_wHqgDkQww

This one shows refraction over variously-shaped region with shallow water. The yellow variously-shaped objects are flat disks placed in water to make water shallow.
