Unformatted text preview: is one single disturbance moving along the medium. A wave train is a succession of pulses. Using a thick rope, we can easily see one single wave pulse moving down the rope. The rope works well to show a pulse because the pulse moves slowly enough to be observed. The reason is that wave speed is proportional to tension in the rope and inversely proportional to density. v = = = density linear tension wavespeed If you have a stretched rubber hose, the tension is high, so the speed is large. In a loose rope, the tension is very low, so the wave speed is small. It also helps that the density of the rope is a lot greater than the density of a rubber hose....
