The Rayleigh Mechanism
How gas molecules scatter the short-wave blues.
- Microscopic Scale
Small Particles, Big Impact
The sky's color begins with nitrogen and oxygen molecules. These gases are much smaller than the wavelength of visible light.
- Discovery
Lord Rayleigh's Insight
In 1871, John William Strutt, the 3rd Baron Rayleigh, quantified how light interacts with these tiny gas particles.
- The Mechanism
Elastic Scattering
When sunlight hits gas molecules, the light is absorbed and immediately re-emitted in all directions. This is Rayleigh scattering.
