123-410 spiral spring for wave experiments

This is a large spiral spring that can be used for experiments by a large number of people. The spiral spring creates waves (pulse waves) that are easy to observe, allowing students to accurately grasp concepts about waves, such as wave superposition, reflection, and phenomena occurring at the boundaries of media. It has the ability to return to its original shape even when stretched 80 times (approximately 9 m). The experiment will be carried out over the entire length of the classroom, allowing many people to participate. Flat wire spring: Closely wound (approximately 170 turns) Winding diameter: 72mm Product code: 123-410
