Physics in Slinky's



Slinky's can perfectly represent the concepts of basic waves. First, if one person yanks the slinky to the left then quickly back once, a pulse is created. If they do this repeatedly, a wave is created. By making bigger waves, the amplitude will increase and by making faster waves, the frequency increases. If the person at the other end of the slinky decided to create waves as well, interference occurs where the two waves meet. If the waves are produced on the same side of the slinky, constructive interference will occur, creating a bigger amplitude where they meet. But if the waves are produced on opposite sides of the slinky, destructive interference occurs where displacements negate each other. By performing different experiments on slinky's, we can observe how waves work by manipulating their characteristics, observing physics in real life.
