Shake Hands with Yourself
★Exhibit Content: Science popularization of concave mirror imaging principles ★Interaction: Manual interaction ★Operation: Visitors extend their hands in front of the mirror to experience the visual phenomenon of shaking hands with themselves. ★Function Overview: This exhibit is equipped with a concave reflective mirror. The concave spherical mirror also follows the law of reflection. When the visitor's hand is placed at twice the focal length on the optical axis, an inverted image of the same size as the hand is formed. The image coincides with the hand, making it seem like shaking hands with oneself, which is very intuitive and vivid. On the other side, the concave mirror and the model are installed inside the display stand, but through the concave mirror, participants can see a real image floating outside, but this visible object cannot be touched. ★Scientific Principle: According to the concave mirror imaging principle, when an object is placed on the central axis of a concave mirror at twice the focal length from the mirror, an inverted real image of equal size is formed. Concave mirrors form images by reflection. Mirrors (including convex mirrors) are not instruments that transmit light but reflect it to form images, and light follows the law of reflection. A concave mirror can not only converge parallel light rays to a focal point but also reflect light rays emitted from the focal point into parallel light. Imaging rules: When the object distance is less than the focal length, an upright, magnified virtual image is formed; the farther the object is from the mirror, the larger the image. When the object distance is greater than 1 times the focal length and less than 2 times the focal length, an inverted, magnified real image is formed; when the object distance equals 2 times the focal length, an inverted, equal-sized real image is formed; when the object distance is greater than 2 times the focal length, an inverted, reduced real image is formed; the farther the object is from the mirror, the smaller the image. The real image formed is on the same side as the object, while the virtual image formed is on the opposite side.
