About this Simulation

This simulation models how light travels in straight lines from a light source, interacts with objects, and enters the observer's eye to create vision. Learners can adjust the lamp height, book position, and viewing angle to explore light paths and understand the fundamental principles of how we see the world around us.

Learning objectives: Understand that light travels in straight lines from a source | Observe how light reflects off objects and enters the eye to enable vision | Investigate the geometric relationship between light source, object position, and observer viewpoint
