Dancing Shadow
★Exhibit Content: Popular science on the straight-line propagation of light and light-shadow changes ★Interaction: Electromechanical interaction ★Operation: Push to adjust the distance between the light source and the models; observe the dynamic changes in the size and shape of the shadows on the background curtain. ★Exhibit Description: The exhibit consists of a white display stand, a slidable light source component, multiple ballet figure models, a stage-shaped backdrop, and a curtain. It is a recommended exhibit from the PopsciCat Exhibit Store. When powered on, the figure models rotate slowly. Visitors manually move the light source to change the relative distance between the light source and the models, projecting dynamic silhouettes onto the rear stage backdrop. As the distance changes, the shadows produce a magnifying and shrinking visual effect. The same model can present completely different projections from different angles, demonstrating light and shadow knowledge in an entertaining stage shadow play format. ★Scientific Principle: Light propagates in a straight line in a uniform medium. When it encounters an opaque object, it is blocked, forming a shadow behind the object. The size of the shadow is determined by the relative distances among the light source, the object, and the projection surface. When the position of the light source changes, the projected outline of the object's contour also changes. The same three-dimensional model can generate silhouette images that differ greatly from the actual shape when projected from different angles.
