Understanding Light Energy

The video tutorial explores the concept of light energy, explaining how light reflection allows us to see objects. It discusses how light is absorbed or reflected by different materials, leading to the formation of shadows. The video categorizes objects into transparent, translucent, and opaque based on their light transmission properties. It also covers the color spectrum of light, how colors are perceived, and the impact of clothing color on heat absorption. The tutorial concludes with a prompt for a quiz to reinforce learning.
