About this Simulation

This simulator models how light refracts (bends) when traveling between air and water. Students can adjust object size, position, and view angle to observe how refraction affects the apparent position and appearance of submerged objects. The interactive tool visualizes light ray paths and demonstrates why objects underwater appear closer than they actually are.

Learning objectives: Understand the principle of light refraction at air-water interfaces | Observe how refraction causes apparent displacement of submerged objects | Explore the relationship between angle of incidence and angle of refraction
