🔦 How Light Travels
Explore the fascinating ways light moves and interacts with objects around us. This quiz focuses on understanding how light travels in straight lines, how shadows form when light is blocked, and how different materials affect the passage of light. You'll discover why some objects are transparent, translucent, or opaque, and learn to predict shadow sizes based on light source position. **What you'll learn:** - Light travels in straight lines from its source - Shadows form when objects block light - Shadow size depends on light source position and object distance - Materials are classified as transparent, translucent, or opaque
