❓ Question of the Day

What is the scientific basis for the blue color of the sky?

Answer: The blue color of the sky is caused by the scattering of sunlight by the tiny molecules of gases (like Nitrogen and Oxygen) and dust particles in the atmosphere. This phenomenon is known as Rayleigh scattering. Since blue light has shorter wavelengths, it is scattered more effectively and prominently in all directions than other colors, making the sky appear blue.
