光の反射・屈折ラボ｜鏡とレンズを実験

This science teaching material for elementary school 3rd grade to junior high school 3rd grade allows students to observe the path of light in real time by moving mirrors, lenses, and light sources.

It allows users to switch between reflection, refraction, and lens experiments, and arrange plane mirrors, convex lenses, concave lenses, glass, and prisms. Students can compare how light rays travel when the angle and refractive index of the equipment are changed, and check their understanding with challenge problems and hints. It also supports saving experiment records.

It's useful when students want to experiment with the properties of light, which are difficult to understand from diagrams alone, by manipulating the equipment.
