Overview This optical instrument demonstrates the principle of light reflection through handson experiments. It helps children understand how light reflects by observing and adjusting the setup, making learning more intuitive and engaging. Key features Rotatable lens for adjustable viewing angles and quick changes to observe how reflection varies with the incident angle Quick disassembly and easy cleaning for fast setup and straightforward maintenance Applicable as a physics experiment and school teaching tool for studying optical reflection Size: approximately 30 cm (11.81 inches) Benefits Supports clear, handson learning of light reflection concepts Reduces lesson setup time and simplifies cleanup, enabling more time for exploration Suitable for frequent classroom use and student projects due to easy maintenance and reuse Specifications Type: optical instrument that uses the principle of light reflection Function: physics experiment, school teaching tool Lens: rotatable; disassembly and cleaning are easy Size: approx 30 cm / 11.81 in Material: not specified Model: not specified Usage scenarios Inclass demonstration: Teacher uses the rotatable lens to show how incident light reflects at different angles on a surface Student experiments: Small groups perform guided experiments to measure reflection angles and compare results with theory Project work or science fair preparation: Students build and describe a simple optical reflection setup to illustrate concepts and outcomes Care and maintenance Disassemble as needed and clean parts between uses Reassemble carefully to preserve alignment and performance for the next session
