This tool allows exploring the curvature of light between two media with the different refractive index. Analyze how light when passing from air to water through a crystal changes its angle of reflection.

It is a Web application that allows you to vary the parameters and observe, in real time, how the graph that represents the evolution of the state of light as it passes through different bodies evolves. We will see on the screen the real values that light adopts depending on different types of materials that we can select, observing how the angle of reflection or refraction of light varies.
