Question
What is the primary reason for the blue color of the
sky?Solution
The sky appears blue primarily due to Rayleigh scattering. This phenomenon occurs when sunlight passes through the Earth's atmosphere, and the shorter wavelengths of light (like blue) are scattered in all directions by the molecules and small particles in the air. Since blue light is scattered more than other colors, the sky appears blue to us.
