Why is the sky blue: So

So, in short, the sky is blue because of Rayleigh scattering, which causes shorter blue wavelengths of light to scatter more than other colors. Our eyes are tuned to see blue more clearly, and the Sun emits more blue than violet light, which is why our daytime sky isn’t purple. Why is the sky blue? Why are sunsets red? Learn about Rayleigh scattering and other physics factors that color the sky. Ultimately, the question “Why is the sky blue?” is not just about physics—it is about the spirit of inquiry. It shows how even the simplest observation can lead to profound truths. The sky is blue and sunsets are red because different colors of light behave differently when they encounter air molecules, known as Rayleigh scattering.
