Why Is the Colour of the Clear Sky Blue? And Why Are the Clouds White? Molecules with a larger size than the wavelength of light experience the scattering effect differently; the phenomenon is known as the Mie effect. 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. Hence, the blue colour scatters the most and is scattered in all directions by the tiny atmospheric ...

The blue light due to its short wavelength is scattered more than the red light of long 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.

Why do the stars twinkle? As a star’s light penetrates the Earth’s atmosphere, every individual stream of starlight is refracted – caused to change direction, slightly – by the various temperature and density layers in Earth’s atmosphere. You might think of it as the light travelling a zig-zag path to our eyes, instead of the straight path the light would travel if Earth didn’t ...
