WebThe sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible. To understand why the sky is blue, we first need to understand a little bit about light. Although light from the Sun looks white, it is really made up of a spectrum of many ... WebMar 28, 2024 · In this sunrise image, the blue sky, yellow Cirrus clouds, and orange Altocumulus clouds result from both Rayleigh and Mie scattering. Rayleigh scattered produces a blue sky and the color the clouds receives. Mei scattering is responsible for the color we see.
