Three Way Linear Light Source Adjustable via screwdriver to direct the light in three directions, enabling precise illumination for optics demonstrations and experiments. Optical Experiments Supports experiments on refraction of light, refraction through a convex lens, and other lens refractions to explore how light bends and focuses. Lenses and Safety Lenses are safe to use and the kit provides a practical teaching tool for optics education in classrooms or labs. Package Includes Biconvex Lens; Single Concave Lens; Glass Tile; Double Concave Lens; Triangular Prism Use Scenarios Classroom demonstration: use the three way light to illuminate lenses and prisms to show how light bends at interfaces and through different lens shapes. Student laboratory work: investigate focal lengths, refraction through convex and concave lenses, and the behavior of light with a triangular prism. Home or selfstudy experiments: perform basic optics observations and simple experiments to reinforce concepts of refraction and lensing with the included components.
