Unusual Shadows
★Exhibit Content: Rectilinear propagation of light and shadow changes ★Interaction: Electromechanical interaction ★Operation: Move the shaped ornaments inside the exhibit platform or rotate the light-emitting device; observe changes in the size and outline of shadows on the projection surface; you can also place your hands in front of the light source to experience shadow play. ★Exhibit Description: The exhibit consists of a platform, light-emitting device, movable shaped ornaments, projection panel, etc., and is a recommended exhibit from the PopsciCat Exhibit Store. Inside the platform, multiple sets of space-themed shaped objects of different shapes are arranged. Visitors can move the ornaments forward, backward, left, and right, or rotate the light source device to intuitively observe changes in shadow form on the projection panel, and independently explore the patterns of how shadow size and outline change with object distance and light source angle. Visitors can also place their hands in front of the light source to engage in shadow play interactive games, observe light and shadow phenomena through fun operations, and be guided to observe the same object from different angles, discover unique structural features of objects, and cultivate observation, thinking, and scientific inquiry abilities. ★Scientific Principle: A shadow is a typical optical phenomenon formed by the rectilinear propagation of light. Light travels forward in straight lines. When it encounters an opaque object, it cannot penetrate, and a dark area lacking light forms behind the object, which is the shadow. Shadows are divided into umbra and penumbra. In the umbra, light is completely blocked, and the shadow color is darker; in the penumbra, only part of the light is blocked, and the shadow is relatively lighter. When the relative positions of the light source, object, and projection surface change, the size and outline of the shadow also change. This exhibit uses an adjustable light source to intuitively demonstrate this principle and help understand the basic characteristics of light propagation.
