Laser Diffraction
★Exhibit Content: Demonstrate the phenomenon of light diffraction and understand the formation principle of diffraction fringes. ★Interaction: Electromechanical interaction ★Operation: 1. Press the button to start the light source. 2. Observe the light diffraction pattern generated on the projection surface to complete the experience. ★Exhibit Description: This exhibit mainly consists of a curved display stand, spotlight, small hole plate, convex lens assembly, projection receiving board, start button, and transparent protective cover. It is a recommended exhibit from the PopsciCat Exhibit Store. Visitors press the start button to turn on the light source; the light passes through the small hole plate, is magnified by the convex lens, and projects a light diffraction pattern onto the receiving board, intuitively reproducing the physical experiment of light diffraction when encountering a small hole, helping visitors observe the diffraction phenomenon of light. ★Scientific Principle: During propagation, when light encounters an obstacle or a small hole, it deviates from the straight-line propagation path and continues to propagate behind the obstacle. This phenomenon is called light diffraction. The alternating bright and dark fringes or halos generated under diffraction are diffraction patterns. This exhibit transforms diffraction effects that are difficult to observe with the naked eye into clearly visible projection patterns, intuitively demonstrating the wave nature of light.
