Calculate the speed of each wave using the average time. Remember, speed = distance/time. 1. Does the speed increase or decrease when you increase the amplitude? 2. Does the speed increase or decrease when you increase the tension in the slinky? (Do not forget to account for the longer distance traveled.) 3. What happens to the wave when it reaches the end of the slinky? (What changes and what stays the same?) Watch carefully to see what the wave does. 4. What happens if you and your partner both start a wave from each end? 5. From your data, which wave is faster P or S? Does this match what you know about wave speed? If not, why do you think that is
