About this Simulation

This simulation demonstrates Fermat's Principle, which states that light travels along the path that takes the least time. Learners can adjust the light path and observe how refraction occurs when light passes between different media, visualizing the relationship between angles of incidence and refraction in real-time.

Learning objectives: Understand Fermat's Principle and its role in explaining light refraction | Explore how light bends at media boundaries and why | Connect geometric optics principles to fundamental physical laws
