We revisit the properties of reflection and refraction in a lab of solving light mazes. Using a limited number of optical tools, including lenses and mirrors, students must guide a ray, or series of rays, of light through a maze.
The properties of lenses, such as their shape and curvature, play unique roles in guiding light in a desired direction. There are analogues to guiding light, however, within the eye itself. Students will learn how the eye collects rays of light from one's surroundings and uses biological lenses to guide the light onto the retina.
