In this project, students will investigate how light refracts through different materials. By measuring the angles of incidence and refraction, they will derive Snell's Law and understand the properties of light. This experiment is both educational and visually appealing.
If light passes through different media, then the angle of refraction will vary according to the refractive index of the material.
