Description

This physics apparatus provides a visual representation of simple harmonic motion and wave mechanics. It features an air-supported spring oscillator system that uses a transparent hose to introduce air, minimizing friction along the track for smooth movement of the transparent sliding block. A visible spring assembly reacts to applied forces. The instrument includes a horizontal scale beam with centimeter markings for measuring displacement. It is mounted on a stable blue rectangular base with black posts. Dimensions: 30 cm length, 9 cm height, 10 cm width.
