Why Is the Colour of the Clear Sky Blue? And Why Are the Clouds White?

Due to the largeness of particles, the light appears white. That is why the clouds, which are made of water droplets, are white.

Blue Sky It is normal to say that the sky appears blue in colour. Have you ever thought about why it appears blue? When sunlight enters the Earth’s atmosphere, it gets scattered by the atmospheric particles. In the spectrum of white light, blue is the colour that has a minimum wavelength.

Thus the light directly from the sun reaching our eye is rich in red colour while the light from all the other directions reaching our eye is the scattered blue light. Therefore the sky in the direction of the sun is blue.
