Catch the Ball
★Exhibit Content: Refraction of Light ★Interaction: Electromechanical Interaction ★Operation: 1. Press the start button, and the ball is blown up by airflow; 2. Observe the ball's position through the viewing window and try to catch the ball; you will find that it seems to become less easy. ★Exhibit Description: The exhibit mainly consists of a ball, airflow device, transparent prism viewing window, etc. Press the start button, and the ball is blown up by airflow; observe the ball's position through the viewing window and try to catch the ball; you will find that it seems to become less easy. Through intuitive visual experience, it vividly demonstrates the principle of light refraction, stimulates visitors' curiosity and desire to explore optical phenomena, provides a lively and interesting carrier for the popularization and dissemination of scientific knowledge, and is a recommended exhibit for the PopsciCat Exhibit Store. ★Scientific Principle: When light enters from one medium to another, its propagation direction changes, and the specific refraction angle depends on the refractive indices of the two media. When visitors try to catch the ball through a specially designed viewing window, they will be surprised to find that due to the refraction of the prism, the ball's image is 'distorted' and shifted from its true position, making the catching action extremely difficult.
