1. Have 2 people hold the opposite ends of a slinky - go maybe 2m apart. Make a transverse wave with a short, sharp, side to side and back motion with your hand so that the hand ends where it started. What observations can you make about a wave? Now make a compression wavve (image 2 below). Make observations about each. 2. Develop a procedure to measure the speed of a wave as it goes down the slinky. (speed = distance/time) 3. Use this procedure to determine what variables affect the speed of wave in a slinky. Be careful to only change one variable at a time if at all possible. Also, how accurately can you measure the speed? Some variables to try, for starters. Tightness (tension) Amplitude Compression vs. transverse waves Etc
