Solution
The reason behind the blue color of the sky is due to a phenomenon called Rayleigh scattering. When sunlight reaches the Earth's atmosphere, it is made up of different colors, each of which has a different wavelength. Blue and violet light have the shortest wavelengths and are scattered in all directions by the gas molecules in the Earth's atmosphere. This scattering of light is what makes the sky appear blue to us.
However, you might wonder why we don't see a violet sky, given that violet light is scattered more than blue light. This is because our eyes are more sensitive to blue light and because sunlight reaches us with less violet light to begin with. Additionally, some of the violet light gets absorbed by the ozone layer in the atmosphere. Therefore, we perceive the sky as blue, not violet.
