The disturbance can move between twolocations without the matter between the locations.Transverse and Longitudinal Waves: In this activity you’ll be considering disturbances that move alonga Slinky that is stretched and then fixed at each end. There are two types of disturbances that can travelalong a stretched Slinky:  A few coils at one end can be pulled quickly in a direction that isperpendicular ortransverseto the line of stretched coils and released; or  A few coils at one end can bebunched together in alongitudinaldirection along the line of stretched coils and released. Video framesof each type of disturbance are shown in Figures 1a and 1b and Figures 2a and 2b.Figure 1a: A single frame showing a transverseFigure 2a: A single frame showing a longitudinal disturbance movingalong a stretched Slinky.disturbance moving along a stretched Slinky.Figure 1b: A single frame showing that the transverseFigure 2b: A single frame showing that the transversedisturbance has moved about 1/2 meter in 1/8thof a disturbance has moved about ½ meter in 1/8thof a second.second.Your task in this assignment is to study movies that show transverse and longitudinal disturbances movingalong a stretched Slinky lying on a very slick (low friction) floor. What happens when just a few coils aredisturbed in a deliberate manner and released? You’ll be asked to think about the process by which thedisturbances propagate along the Slinky, measure the wave speeds, and consider what properties of theSlinky will affect the speed of the waves.Before starting this activity, you should view the “slow-mo” versions of the transverse and longitudinalQuickTime movies entitled<SlinkyWave_T01(slow-mo).mov>and<SlinkyWave_L10(slow-mo).mov>.Notes about the Movies:The waves on this Slinky are moving at a rate of over 4 m/s, so we used a highspeed video camera to record the motion at 125 frames per second (fps). We have created two sets ofmovies to enable you to observe and analyze Slinky waves. One set of movies shows the frames beingreplayed in “slow-mo” at only 15 fps so you can observe the motion. The other set can be used foranalysis using the LoggerProsoftware. They are labeled “hi-speed”.
