Light-Trace Foucault Pendulum
★Exhibit Content: Earth's rotation phenomenon, Coriolis force, law of inertia ★Interaction: Electromechanical interaction ★Operation: Press the start button to start the base rotation; use your hand to push the pendulum wire to make the pendulum swing naturally; observe the light traces left by the pendulum's ultraviolet light on the photosensitive base, and compare the offset changes of the light traces as the base rotates. ★Exhibit Description: The main body of the exhibit consists of a circular platform, a metal suspension bracket, a double-pulley suspension mechanism, a pendulum with ultraviolet light, a photosensitive base, a transparent cylindrical protective cover, and an electrical control system. It is a recommended exhibit from the PopsciCat Exhibit Store. A rotating base is embedded inside the circular platform. Directly above the base, a Foucault pendulum is suspended via a metal bracket and double-pulley structure. The pendulum has a built-in ultraviolet light source. The surface of the base is covered with photosensitive material. An external transparent cylindrical protective cover protects the photosensitive disc while allowing easy observation. When the pendulum swings, the ultraviolet light continuously leaves a visual swing trajectory on the rotating base. ★Scientific Principle: When a Foucault pendulum swings, without external interference, the plane of oscillation maintains a fixed spatial orientation due to inertia. This exhibit simulates the rotation of the ground through the base, and the ultraviolet light leaves traces on the photosensitive rotating disc, intuitively demonstrating the deflection effect caused by the Coriolis force, simulating the classic Foucault pendulum experiment to prove that the Earth rotates. At different latitudes on Earth, the Coriolis force varies in strength, so the rate of deflection of the Foucault pendulum's plane of oscillation also differs.
