About this Simulation

This interactive simulation models how light from a single source creates shadows when an object blocks its path to a screen. Learners can adjust the light source position, observe how shadow size and shape change dynamically, and explore the geometric relationships between light, object, and shadow formation in real time.

Learning objectives: Understand how light travels in straight lines and creates shadows | Investigate how light source position affects shadow size and appearance | Explore the geometric principles of light blocking and projection
