This set is a physical optical teaching science experiment equipment based on an optical bench, providing a stable platform for a variety of optical experiments. Key components - Lenses: used to explore the principles of refraction, focusing, and image formation. - Pinhole imaging component: lets students observe light traveling in a straight line and the formation of images. Education value - A comprehensive physics lab set that helps students understand optics concepts and laws through hands-on experiments. Benefits and what makes it stand out - Function and performance: the optical bench offers a stable platform that supports precise alignment and repeatable results during experiments. - Independent learning: enables students to conduct experiments on their own, enhancing practical skills and understanding of optical knowledge. - Teaching effectiveness: essential for teaching and learning physical optics in a practical, observable way. Use scenarios - In-class demonstrations: illustrate lens behavior, refraction, focusing, and image formation to the whole class. - Student-led labs: provide hands-on opportunities to perform optics experiments with guided exploration. - Independent study: support self-guided practice to reinforce optical concepts and measurement skills. Notes - Size and material details are not specified in the description; please refer to product specifications for exact dimensions and construction.
