About this Simulation

This simulation models how light intensity varies with distance from a source and changes when passing through thin lenses. Students can adjust source size, observation range, and lens properties to observe real-time effects on light intensity distribution. The interactive visualization helps learners understand the inverse square law and optical focusing principles.

Learning objectives: Understand the relationship between distance and light intensity | Explore how lenses focus and modify light intensity patterns | Apply mathematical principles to predict intensity changes in optical systems
