Periscope
★Exhibit Content: Popular science on the law of reflection and the principle of two-time reflection imaging by plane mirrors ★Interaction: Static interactive display ★Operation: Aim your eyes at an observation target, then look through the viewing port below the mirror tube to experience observing objects from a lower position, and intuitively understand the application of light reflection in periscopes. ★Exhibit Description: The exhibit consists of a Q235 sheet metal baked-paint base, custom steel pipe support structure, 2 high-reflectivity optical glass mirrors, transparent acrylic protective components, etc. It is a recommended exhibit by KexMall. Inside, two sets of mirrors are placed parallel to each other and perpendicular to the ground. After two reflections, light transmits the scene from above to the viewing port, achieving the effect of 'observing high places from a low position', suitable for audiences of all ages to explore the mysteries of optics. ★Scientific Principle: This exhibit is based on the law of reflection and the principle of two-time reflection imaging: Law of Reflection: When light encounters a smooth reflective surface (optical mirror), it reflects according to the rule that 'the reflected ray, incident ray, and normal lie in the same plane, and the angle of reflection equals the angle of incidence'; Two-time Reflection Imaging: The two sets of mirrors are parallel to each other and perpendicular to the ground. Light undergoes the first reflection by the upper mirror (changing direction by 90°), then the second reflection by the lower mirror (changing direction by 90° again), ultimately accurately transmitting the scene from above to the viewing port, achieving the effect of 'observing high places from a low position'; This principle is the core working logic of periscopes, widely used in daily life, military, and other fields, and is a classic optical science exhibit.
