The color of the sky depends largely upon the wavelengths of the incoming light but air molecules mostly nitrogen and oxygen and dust particles also play important roles When the sun is high

The sky is blue because sunlight collides with gas molecules in the atmosphere and shorter wavelengths of light scatter far more than longer ones This process called Rayleigh

Everyone loves a clear sunny day but have you ever looked up and wondered exactly why is the sky blue The answer lies in the physics of when sunlight passes through the atmosphere
