Understanding Why the Sky is Blue

The video explains why the sky is blue by exploring the nature of sunlight, which contains all colors of the rainbow. It describes how light behaves when it passes through a prism, separating into different colors. The video further explains that when sunlight enters Earth's atmosphere, it scatters due to tiny air particles, with blue light scattering the most, making the sky appear blue. The video encourages viewers to explore and observe the sky.
