About this Simulation

This interactive simulation demonstrates the fundamental principle that light travels in straight lines through uniform media. Learners can observe light ray paths, explore how obstacles affect light propagation, and visualise the formation of shadows. The video-based approach provides clear visual representation of optical concepts in an engaging, interactive environment.

Learning objectives: Understand that light travels in straight lines through transparent media | Explain how straight-line light propagation creates shadows | Apply the principle of light rays to solve simple geometric optics problems
