31. $500 Question from C3 Your prediction of what will happen when a wave moves from a thinner substance such as water, into a thicker substance, such as oil; be sure to use the concepts of speed and refraction in your answer.

32. $500 Answer from C3 Back to Jeopardy What is the speed of the wave depends on the medium through which it passes, so the speed will change when the wave passes from water into oil. I predict that the speed will decrease because it takes more force to move the heavier oil. The wave will probably also bend, or refract, as it moves from one medium into the other?
