Refraction Optical Experiment Set Versatile design The set covers a range of optical components, including concave and convex lenses. By adjusting and combining these parts, students can observe light refraction and focusing, expanding the diversity and depth of experiments. Practical learning This kit provides a handson opportunity for middle school physics students to study optics. By working with concave and convex lenses and lasers, students can directly observe refraction phenomena and deepen their understanding of physical optics. Intuitive teaching By watching the refracted laser paths and spot forms on different lenses, students can intuitively grasp the propagation laws and core principles of light. Easy operation The kit includes concave and convex lenses, threeway lasers, assembly guides, and experiment instructions. It is designed for straightforward setup, enabling students to perform experiments reliably and obtain clear results.
