Physics Optics Experiment Lighting Device Clear, hands on tool for exploring light reflection and refraction. This ABS lighting device is designed for classroom use, science fairs, and home experiments to make abstract optical concepts visible and intuitive. Key benefits Demonstrates the principles of light reflection and refraction in a simple, repeatable way to support lesson plans and lab activities. Durable ABS construction for repeated classroom use and easy handling by students. Helps students visualize how light behaves as it crosses boundaries and reflects from surfaces, improving conceptual understanding through practical observation. Compact and lightweight for easy setup, storage, and transport between classrooms or labs. Features and functions Purpose built to show refraction and reflection phenomena using a focused light source and transparent interfaces. Suitable for guided experiments, demonstrations, and independent student investigations. Clear design that supports real time observation and measurements during experiments. Specifications Color: Three primary colors available. Specification for this unit: Green. Material: ABS Size 1: Approx. 8 x 12 cm (3.15 x 4.72 in) Size 2: Approx. 8 x 12.50 cm (3.15 x 4.92 in) Weight: Approx. 65 g, 70 g, or 75 g depending on model Package contents 1 Piece Physics Optics Experiment Lighting Device Use scenarios Classroom demonstration: Project the light through the device to show how incidence angle affects refraction and reflection during a teacher led lesson. Lab experiment: Students measure angles of incidence and refraction to verify Snell type relationships and practice data collection and analysis. Science fair or home project: Create clear visual displays of light bending and reflection to explain optics concepts to an audience. Notes Please allow a 0 to 1 cm variation due to manual measurement. Actual color may vary slightly from images due to monitor differences.
