Waves on a Coil Spring

Hold one end  of the coil spring on the floor, pull the other end until the spring is reasonably tight. Then generate a pulse.

The pulse, as defined in physics, is the transmission of energy through some type of medium, such as a rope or a coiled spring.  The speed of the pulse will not change, as long as it continues to travel along in the same medium.  It will move at a steady and consistent speed.  The shape of the pulse will tend to do the same, however it may be influenced by factors such as whether it approaches the next connection point as a "free end" or a "fixed end".  Both these ending points can affect the shape of the pulse.
