AP Physics 2: Waves 6: Refraction 1: 1-Dimensional Waves
The wave travels from the small wave machine to the large one. Because the speed is slower on the larger machine, the refracted wave becomes shorter. Because the wave is reflected off of the slower medium (large machine), the upward incident wave hump turns into a downward reflected wave hump.

AP Physics2: Waves 7: Refraction 2: 2-Dimensional Waves and the Law of Refraction
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. Please see: Refraction of Waves http://www.youtube.com/watch?v=7BIc7Oonru0 by Saint Mary's University Physics & Astronomy in Canada
