Transverse Wave: A wave that vibrates at a right angle. Shown by the pulling of the spring to one side at a right angle.
Periodic Wave: Regular timed disturbances in a medium. Displayed by the constant moving of the spring side to side.
Longitudal wave: A wave in the same direction as the motion provided. Displayed by the pulling back on the spring and letting go to create a line of movement.
Pulse wave: A wave done only once, which creates a ripple effect in the medium. Displayed by the one time movement of the spring which then moved the spring all the way to the other end.
