About this Simulation

This interactive simulation models how light refracts when passing between water and air, allowing learners to manipulate incident angles, wavelengths, and amplitude to observe optical behaviour. Investigate the relationship between refractive indices and light bending, exploring why rainbows form and how different wavelengths behave differently in various media.

Learning objectives: Understand how refractive index affects light refraction at boundaries | Apply Snell's law to predict light ray paths through different media | Explore wavelength-dependent optical effects and their role in rainbow formation
