Visual demonstration of how light changes its direction when moving between media, clearly illustrating the deflection at interfaces and how light propagates across different substances on a demarcation plane. Comprehensive optics experiment kit for a wide range of tasks, including plane mirror reflection, diffuse reflection, convex mirror reflection, concave mirror reflection, light refraction, convex lens refraction, and trigonometry refraction, making it a practical teaching aid for mastering complex physics. Key components and performance: Three way laser source produces bright and clear light, with the light angle adjustable. The kit also includes a prism lens made of quality acrylic, ensuring light transmission and a vivid refraction effect for insightful learning. Practical benefits: provides a reliable, allinone solution for visualizing core optics concepts, supporting clear demonstrations and handson experimentation in educational settings. Use scenarios: Inclass demonstration of light behavior at media boundaries, showing deflection and how light can to the original medium across the demarcation plane. Student lab practice covering plane, convex, and concave mirror reflections, as well as light and lens refraction experiments to reinforce theory. Independent study and analysis of refraction using trigonometry with the acrylic prism, aided by the adjustable laser for precise alignment.
