Sunlight looks white but is actually a mix of all colors. When it enters Earth's atmosphere, these colors spread out. This process is key to understanding the sky's color.
Rayleigh Scattering Explained
Rayleigh Scattering Explained
Blue skies result from Rayleigh scattering. It occurs when light interacts with small particles in the atmosphere, scattering shorter wavelengths (blue) more than longer ones (red).
Atmospheric Influence
Atmospheric Influence
The sky's hue varies with the atmosphere's composition. Pollutants and particles change the scattering process, sometimes leading to different sky colors.
