This physics demonstration apparatus helps students visualize mechanical wave concepts on a desktop. It features a double-spring oscillator configuration with two coiled springs extending in opposite directions from a central yellow mounting block. A built-in horizontal beam functions as a scale marked in centimeters for measuring displacement, amplitude, and equilibrium points. The setup is supported by a stable white rectangular base and a vertical metal rod. Overall dimensions: 45 cm length, 43 cm height.
