Understanding Shadows and Light

The video introduces the concept of shadows through a playful interaction, explaining how shadows are formed due to the properties of light traveling in straight lines. It discusses how shadows change with the position of the light source and provides examples from everyday life. The video also covers the historical use of light properties in inventions like sundials and explains natural phenomena such as solar and lunar eclipses. The aim is to enhance understanding of light and its role in creating shadows.
