Ginsberg Scientific Longitudinal Wave Demonstration Model is used to show resonant waves such as propagation, reflection and interference. Model is built of two cast iron support sides and a white cloth background. A spring is suspended on hold arms with two adjustable weights on each side, which gives the vibration that influences the wave frequency. It includes instruction manual.
- Two cast-metal supports (15.25 x 9.5 in./38.7 x 24.1 cm) extend with connector rods to make frame
- White cotton cloth backing increases demonstration visibility
- 3 in. (7.6 cm) spring stretches between frame ends and can be set up to 44 in. (112 cm) apart
