Optical experiments include refraction of light, convex lens refraction, and lens refraction demonstrations. Threeway linear light source can be adjusted by using a screwdriver to change the direction of light. The Physics Optical Experiment set will give your child an understanding of physical optics and make learning easier. The lens is safe to use and serves as a practical teaching toolkit for handson learning. Use scenarios: At home: guide your child through basic optics experiments to observe how light bends and how lenses affect light paths. In the classroom or tutoring: demonstrate core optics concepts with adjustable light direction and lens demonstrations to reinforce theory. Science projects or clubs: compare different lens configurations and light paths to develop experiments and presentations.
