What are some useful applications of refraction?
One interesting example of wave behavior is refraction, which is the bending of a wave as it enters a new medium at an angle. Do Internet research on refraction and find out about some of the useful applications of this behavior. Create a multimedia presentation on refraction that includes text, diagrams, and photos, and deliver the presentation to the class.
