Usage Tips:This Optics Experiment Set serves as a comprehensive solution for performing optical experiments including plane mirror reflection, diffuse reflection, convex mirror reflection, concave mirror reflection, light refraction, convex lens refraction, trigonometry refraction, making it a perfect teaching aid to master complex physics with ease. Our Physics Optics Experimental Set visually demonstrates how light changes its direction of propagation when it shifts from one medium to another, clearly illustrating the deflection phenomenon of light at the junction of different media, and how light changes its direction of propagation and returns to its material when it propagates to different substances on the demarcation plane. The Optics Experimental Kit features a Three way laser source that produces bright and clear light, and the light's angle can be freely adjusted. The kit also contains a Prism lens made of high-quality acrylic, ensuring excellent light transmission, and a vivid refraction effect for more insightful learning. The set includes a broad range of components such as Light Holder, Periscope, F-Shaped , Light Trichromatic Illuminator, F-Shaped Holder, Protractor, Shade Plate, Convex Lens Concave Lens, Small Aperture Plate, Imaging Plate, and much more. These components support experiments, improving understanding and application of optics in real-life situations. The actual product may have slight color differences or differences, which does not affect use. Colour:orange Material:plastic Package Contents: 1 x Optics Experiment Set Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
