Visualizes how light changes direction when moving between media, clearly illustrating the deflection at interfaces and how propagation direction relates to the medium at the boundary. Provides a comprehensive optics experiment kit for multiple core experiments, including plane mirror reflection, diffuse reflection, convex mirror reflection, concave mirror reflection, light refraction, convex lens refraction, and trigonometric refraction, making it a practical teaching tool for mastering complex physics concepts. Features a threeway laser source that produces bright, clear light and can be adjusted, along with a prism lens made of quality acrylic that ensures light transmission and a vivid refraction effect. Key attributes: quality acrylic prism lens; adjustable threeway laser source; supports a wide range of fundamental optics experiments; designed to facilitate clear, handson learning of light behavior. Use scenarios: Inclass demonstrations to show how light behaves at media boundaries and how reflection and refraction occur with different optical elements. Laboratory activities exploring plane, convex, and concave mirrors, as well as refraction through lenses and prisms. Student practice with trigonometric refraction and angle measurements to reinforce theoretical concepts.
