Standing waves are a common phenomenon usually shown through the vibrations of bridges or springs. Horizontal standing waves are produced in a lab by students shaking cords, springs and bungee cords. However, standing waves can also be produced in a vertical fashion by a single student. Using the new nylon Spring Wave, students are able to produce vertical standing waves easily and calculate the speed of the spring. This is a great little "twist" on the age-old standing wave lab that you have in your arsenal.
