💡 How Light Travels
Light is a form of energy that travels incredibly fast in straight lines. When light encounters an object, shadows are formed. This quiz explores the properties of light, how shadows are created, and how to predict shadow position and size based on light source location and object placement. You will use ray diagrams to understand light behavior and shadow formation. **What you'll learn:** - Light travels in straight lines at extremely high speeds - Shadows form when light is blocked by opaque objects - Shadow size and position depend on light source location and object distance - How to interpret and create ray diagrams to show light paths
