Demonstration Wave Spring - WA-7334



The Demonstration Wave Spring is ideal for illustrating mechanical wave properties such as frequency, wavelength and interference. Because it's not as stiff as the Snakey, the Demonstration Wave Spring provides a different medium in which to study waves. Two hooks on either end allow students to stretch this spring to a length of 8 meters.

It has a diameter of 2.3 cm and an unstretched length of 80 cm.
