This Lighting Device for Physics Optics Experiment is well suited for teachers and students, enabling handson experiments that clarify complex concepts in physics. It intuitively demonstrates the principles of light refraction and reflection, helping learners see how light bends and bounces in different media for engaging, credible education. A versatile resource for anyone looking to deepen their understanding of optics and to foster curiosity in science through practical exploration. Constructed from ABS plastic, the device offers durability and safe handling in classroom environments while supporting comprehensive exploration of optical phenomena. Function and performance: designed to deliver reliable, observable demonstrations of reflection and refraction using common light sources and basic optics setups; compact form facilitates classroom use and easy integration into lesson plans. Compatibility and use: suitable for standard optics demonstrations in science curricula; adaptable to a variety of introductory optics activities and demonstrations. 23 practical use scenarios In a school physics class, teachers use the device to demonstrate refraction through air, glass, and water media, allowing students to observe and compare angles of incidence and refraction. In a student lab, pairs conduct guided experiments to explore how incident angles affect the reflected and refracted rays, fostering handson inquiry and data collection. In a science club or outreach setting, instructors run live demonstrations to explain basic optics concepts to newcomers, helping to visualize how light behaves when encountering different materials.
