Double-Slit Experiment
★Exhibit Content: Demonstrate the double-slit interference of light, intuitively understand the wave-particle duality of light ★Interaction: Electromechanical interaction ★Operation: 1. Press the start button to turn on the laser source 2. Rotate the adjustment knob to change the distance between the double slits and the receiving screen 3. Observe the alternating bright and dark interference fringes on the receiving screen to complete the experience ★Exhibit Description: This exhibit mainly consists of an arc-shaped display stand, laser emission component, movable double-slit plate, receiving projection screen, adjustment knob, start button, and transparent protective cover. It is a recommended exhibit from the PopsciCat Exhibit Store. Visitors press the start button to light up the laser, turn the knob to adjust the distance between the double slits and the light screen, and can observe alternating bright and dark interference fringes on the screen, simulating and reproducing the classic Young's double-slit interference experiment, concretely demonstrating the wave properties of light. ★Scientific Principle: Double-slit interference is a classic physics experiment that proves light has wave properties. After the laser passes through two slits, two coherent light beams are formed. The two beams superimpose and interfere; peaks overlapping with peaks form bright fringes, while peaks canceling with troughs form dark fringes. An alternating bright and dark interference pattern appears on the screen, intuitively demonstrating the wave properties of light.
