ThreeWay Linear Light Source The unit provides adjustable illumination in three directions. Use a screwdriver to set the light direction, allowing precise alignment of light paths for accurate observation of optical phenomena and demonstrations. Optical Experiments and Refraction Supports practical refraction experiments with lenses to demonstrate how light bends through different shapes. Designed to showcase lens behavior with both biconvex and concave configurations during handson learning. Safe and Easy to Use Teaching Kit Lens components are designed for safe handling and straightforward use, making this a practical tool for classrooms and independent study. Its simple setup supports effective teaching and student engagement. Package Includes Biconvex Lens Single Concave Lens Glass Tile Double Concave Lens Triangular Use Scenarios Classroom demonstrations of refraction and lens behavior during physics lessons. Studentled experiments exploring how different lenses affect light paths and focus. Home or hobby science projects for handson optics exploration.
