🧪 3D Blue Sky Rayleigh Scattering

3D Why is the Sky Blue – Rayleigh Scattering (∝1/λ⁴): Shorter wavelengths are scattered more strongly than longer ones. This same mechanism explains both the blue sky and a red sunset.

⚙ Under the hood

This simulation visually explains Rayleigh scattering – the phenomenon responsible for the blue color of the sky. Users can adjust parameters like wavelength and air density to observe how light interacts with atmospheric particles.
