The sky appears blue because of Rayleigh scattering. 🌌

Here is the quick breakdown:

• Sunlight: Contains all the colors of the rainbow.
• Atmosphere: Filled with gases (mostly nitrogen and oxygen).
• Scattering: As sunlight hits the atmosphere, shorter blue wavelengths are scattered in every direction by gas molecules more strongly than longer red wavelengths.

When you look up, your eyes catch this scattered blue light from all over the sky! ☀️➡️🔵

The sky appears blue because of Rayleigh scattering.

As sunlight reaches Earth's atmosphere, it is scattered in all directions by the gases and particles in the air. Blue light travels in shorter, smaller waves and is scattered more strongly than the other colors, which is why we see a blue sky! ☀️🌈
